ASTM B557-15(2023)(Test Method)

Standard Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products

SIGNIFICANCE AND USE
4.1 Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances.
4.2 The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments.
4.3 These test methods are considered satisfactory for acceptance testing of commercial shipments and have been used extensively in the trade for this purpose.
SCOPE
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8, which cover the tension testing of all metallic materials.
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: Foil is sheet metal less than 0.0079 in. thick. There is an overlap in the thickness range 0.006 to 0.0079 in. defined for foil and sheet. Sheet products in this thickness range are supplied to sheet product specifications and foil products in this thickness range are supplied to foil product specifications. Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material.
Note 2: A complete metric companion to Test Methods B557 has been developed—Test Methods B557M; therefore, no metric equivalents are presented in these test methods.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM B557M-15(Test Method)

Standard Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products (Metric)

SIGNIFICANCE AND USE
4.1 Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances.
4.2 The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments.
4.3 These test methods are considered satisfactory for acceptance testing of commercial shipments and have been used extensively in the trade for this purpose.
SCOPE
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8M, which cover the tension testing of all metallic materials.
Note 1: These metric test methods are the equivalents of those in Test Methods B557, and are compatible in technical content except for the requirement of longer gage lengths for round specimens.
Note 2: Foil is sheet metal less than 0.20 mm thick. There is an overlap in the thickness range 0.15 to 0.20 mm defined for foil and sheet. Sheet products in this thickness range are supplied to sheet product specifications and foil products in this thickness range are supplied to foil product specifications. Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Practice for Codification of Unalloyed Magnesium and Magnesium-Alloys, Cast and Wrought

ABSTRACT
This practice provides a system for the codification of unalloyed magnesium and magnesium alloys in the cast and wrought forms. Code designations shall be based on their chemical composition limits. For alloys, designations shall consist of not more than two letters representing the alloying elements specified in the greatest amount, followed by the respective percentages and a serial letter. The letters that represent the alloying elements are: A for aluminum; C for copper; E for rare earths; J for strontium; K for zirconium; L for lithium; M for manganese; Q for silver; S for silicon; T for tin; V for gadolinium; W for yttrium; and Z for zinc. For unalloyed metals, designations shall consist of the specified minimum purity, followed by a serial letter. For both cases, the full name of the base metal precedes the designation, but is omitted for brevity when the base metal being referred to is obvious.
SCOPE
1.1 This practice provides a system for designating unalloyed magnesium and magnesium-alloys that have been used commercially since 1952, and thus is intended to be the registration source for unalloyed magnesium and magnesium-alloys. A record of designations along with the established compositions is given in Table 2.
1.2 The equivalent Unified Numbering System (UNS) alloy designations shown in the appendixes are in accordance with Practice E527.

ASTM E155-10(Specification)

Standard Reference Radiographs for Inspection of Aluminum and Magnesium Castings

SIGNIFICANCE AND USE
These radiographs are intended for reference only but are so designed that acceptance standards, which may be developed for particular requirements, can be specified in terms of these radiographs. The illustrations are radiographs of castings that were produced under conditions designed to develop the discontinuities. The radiographs of the 1/4-in. (6.35-mm) castings are intended to be used in the thickness range up to and including 1/2 in. (12.7 mm). The radiographs of the 3/4-in. (19.1-mm) castings are intended to be used in the thickness range of over 1/2 in. to and including 2 in. (51 mm). The grouping and system of designations are based on considerations of the best practical means of making these reference radiographs of the greatest possible value.
Film DeteriorationRadiographic films are subject to wear and tear from handling and use. The extent to which the image deteriorates over time is a function of storage conditions, care in handling and amount of use. Reference radiograph films are no exception and may exhibit a loss in image quality over time. The radiographs should therefore be periodically examined for signs of wear and tear, including scratches, abrasions, stains, and so forth. Any reference radiographs which show signs of excessive wear and tear which could influence the interpretation and use of the radiographs should be replaced.
SCOPE
1.1 These reference radiographs illustrate the types and degrees of discontinuities that may be found in aluminum-alloy and magnesium-alloy castings. The castings illustrated are in thicknesses of 1/4 in. (6.35 mm) and 3/4 in. (19.1 mm). The reference radiograph films are an adjunct to this document and must be purchased separately from ASTM International if needed.
1.2 These film reference radiographs are not intended to illustrate the types and degrees of discontinuities found in aluminum-alloy castings when performing digital radiography. If performing digital radiography of aluminum-alloy castings, refer to Digital Reference Image Standard E2422. Magnesium-alloy digital reference images are not currently available from ASTM International.
1.3 This document may be used where no other applicable document exists, for other material thicknesses for which it has been found to be applicable and for which agreement has been reached between the purchaser and the manufacturer.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—Vol I: The set of reference radiographs consists of 13 plates covering discontinuities in aluminum-alloy castings and 10 plates covering discontinuities in magnesium-alloy castings. Each plate is held in an 81/2 by 11-in. (216 by 279-mm) cardboard frame and each plate illustrates eight grades of severity for the discontinuity in approximately a 2 by 2-in. (51 by 51-mm) area. The cardboard frames are contained in a 101/2 by 111/2-in. (267 by 292-mm) ring binder. The reference radiographs are not impacted by this revision. There have been no revisions to the adjunct reference radiographs since original issue. The adjunct reference radiographs of any issue remain valid and may be used to this standard.
Vol. II: The set of reference radiographs consists of four plates covering discontinuities in magnesium-alloy castings only. Each plate is held in an 81/2 by 11-in. (216 by 279-mm) cardboard frame and illustrates eight grades of severity for the discontinuity (with the exception of discrete discontinuities, where only one example of each discontinuity is...

ASTM B557-10(Test Method)

Standard Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products

SIGNIFICANCE AND USE
Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances.
The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments.
These test methods are considered satisfactory for acceptance testing of commercial shipments and have been used extensively in the trade for this purpose.
SCOPE
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, excepting aluminum foil , and are derived from Test Methods E8, which cover the tension testing of all metallic materials.
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material.
Note 2—A complete metric companion to Test Methods B557 has been developedTest Methods B557M; therefore, no metric equivalents are presented in these test methods.

ASTM G97-97(2007)(Test Method)

Standard Test Method for Laboratory Evaluation of Magnesium Sacrificial Anode Test Specimens for Underground Applications

SIGNIFICANCE AND USE
This test is a guide for evaluating magnesium anodes. The degree of correlation between this test and service performance has not been fully determined.
SCOPE
1.1 This test method covers a laboratory procedure that measures the two fundamental performance properties of magnesium sacrificial anode test specimens operating in a saturated calcium sulfate, saturated magnesium hydroxide environment. The two fundamental properties are electrode (oxidation potential) and ampere hours (Ah) obtained per unit mass of specimen consumed. Magnesium anodes installed underground are usually surrounded by a backfill material that typically consists of 75 % gypsum (CaSO4·2H2O), 20 % bentonite clay, and 5 % sodium sulfate (Na2SO4). The calcium sulfate, magnesium hydroxide test electrolyte simulates the long term environment around an anode installed in the gypsum-bentonite-sodium sulfate backfill.
1.2 This test method is intended to be used for quality assurance by anode manufacturers or anode users. However, long term field performance properties may not be identical to property measurements obtained using this laboratory test.
Note 1—Refer to Terminology G 15 for terms used in this test method.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautions, See Section 7 and Paragraph 8.1.1.
