A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification cover
3、s magnesium-alloy extrudedbars, rods, profiles, tubes, and wire of the composition given inTable 1.1.2 The values stated in either inch-pound or SI units are tobe regarded separately as standards. The SI units are shown inbrackets or in separate tables or columns. The values stated ineach system are
4、 not exact equivalents; therefore, each systemmust be used independent of the other. Combining values fromthe two systems may result in nonconformance with thespecification.1.3 Unless the order specifies the “M” specification desig-nation, the material shall be furnished to the inch-pound units.2.

Except as otherwise specified inthe contract or order, the producer or supplier may use his ownor any other suitable facilities for the performance of theinspection and test requirements s
22、pecified herein, unless dis-approved by the purchaser at the time the order is placed. Thepurchaser shall have the right to perform any of the inspectionsand tests set forth in this specification where such inspectionsare deemed necessary to assure that material conforms toprescribed requirements.6.
23、 Chemical Composition6.1 LimitsThe bars, rods, profiles, tubes, or wire shallconform to the chemical requirements in Table 1.6.2 Number of SamplesThe number of samples taken fordetermination of chemical composition shall be as follows:6.2.1 When samples are taken at the time extrusion ingotsare cast
24、 for determination of conformance to Table 1, onesample shall be taken for each group of ingots of the samealloy, poured at the same time, from the same source of moltenmetal when a batch process is employed. In cases where acontinuous casting process is employed, one sample shall betaken for each q
25、uantity of material cast equivalent in size(weight or volume) to the last holding vessel before casting or5000 lb 2270 kg, whichever is less. Ingots not conforming toTable 1 shall be rejected.6.2.2 Unless compliance is established by 6.2.1, sampling ofthe finished product shall be in accordance with
26、 Practice E55.One sample shall be taken for each 4000 lb (2000 kg) or lessof material comprising the lot, except that not more than oneanalysis shall be required per piece.TABLE 1 Chemical RequirementsANOTE 1Analysis shall regularly be made only for the elements specifically mentioned in this table.
27、 If, however, the presence of other elements issuspected or indicated in the course of routine analysis to be in amounts greater than the specified limits, further analysis shall be made to determine thatthe total of these other elements is not in excess of the limits specified in the last column of
28、 the table.NOTE 2The following applies to all specified limits in this table: For purposes of acceptance and rejection, an observed value or a calculated valueobtained from analysis should be rounded-off to the nearest unit in the last right-hand place of figures used in expressing the specified lim

38、hodsThe tension tests shall be made inaccordance with Test Methods B 557 and B 557M.7.5 RetestsIf any tension specimen fails to conform to therequirements prescribed in Table 2, two additional specimensshall be selected and tested from other bars, rods, profiles,tubes, or wire in the lot. If either
39、of these specimens fails toconform to the applicable requirements, the material may berejected. If, however, the failure of the specimens to conform tothe requirements is the result of an inadequate thermal treat-ment, the material may be reheat treated and resampled inaccordance with 7.2.TABLE 2 Te
