ScopeThis SAE Standard covers the most common magnesium alloys used in wrought forms, and listschemical
5、 composition and minimum mechanical properties for the various forms. A general indication of theusage of the various materials is also provided.1.1 IntroductionMagnesium wrought alloys are produced and fabricated by all the common productionmethods such as rolling, extrusion, and forging. Forms ava
6、ilable are sheet, plate, wire, rod, bar, shapes,tubes, forgings, and impact extrusions. Magnesium alloys can be formed by bending, drawing, spinning, andpressing. The work is generally done hot except for simple operations. When done hot, magnesium alloyshave exceptional workability. The temperature
7、 used varies from 300750F (149399C), depending onoperation, alloy, and condition. All of the wrought alloys can be joined by adhesive bonding, spot welding,riveting, and bolting. Most of them are readily fusion welded and some do not require stress relief afterwelding. As with the cast alloys, all w
8、rought alloys machine readily.The temper designations used for wrought magnesium are similar to those used for aluminum alloys. Temperdesignations are covered by ASTM B 296-67 (1972), Recommended Practice for Temper Designations ofMagnesium Alloys, Cast and Wrought. Mechanical properties are obtaine
9、d by standard ASTM procedures.The tensile and compressive yield strength is taken at an offset of 0.2% from the initial modulus line.Table 1 lists similar ASTM, AMS, Military, and Federal specifications covering the SAE wrought alloys in thisSAE Standard.SAE J466 Reaffirmed DEC89-2-2.

Sheet And Plate:3.1 IntroductionMagnesium alloy sheet is r
15、olled to a thickness of 0.006-0.249 in (0.15-6.32 mm). Plate is0.250in (6.35 mm) or over in thickness. Dimensional tolerances used are the same as for aluminum alloys andare given in the current issue of ASTM B 90-70.Magnesium sheet and plate is flattened thermally and can be obtained commercially,
16、with smaller flatnesstolerances than for most other metals. One grade of specially flattened plate is used extensively as toolingplate. The annealed condition (0) is used for maximum formability and ductility. The cold rolled and partiallyannealed condition (H24) has better strength and less ductili
17、ty than the 0 temper.

29、med DEC89-5-M16100 is not as strong as M11311. It has good formability and excellent weldability and does not requirestress relieving after welding. It is used in place of M11311 primarily in tanks and large structures where stressrelieving would be a problem. It is available in either the annealed
30、(0) or cold rolled and partially annealed(H24) conditions.M13310 was developed primarily for elevated temperature use in the 300700 F (149371 C) range. It ismore costly than M11311 and M16100. M13310 alloy has excellent weldability and good formability. It isavailable in either the annealed (0) or c
31、old rolled and partially annealed (H24) conditions. It has been usedprimarily in aircraft and missiles. M13210 was also developed for elevated temperature use in aircraft,missiles, and electronics.M14141, containing 14% Li, is the only magnesium alloy with a body-centered cubic rather than hexagonal
32、-close-packed crystal structure. It was developed as a very ductile and highly formable alloy.4. Extrusions4.1 IntroductionMagnesium alloys in general are extruded to size without subsequent drawing operations.Some sizing or shaving has been used to get better tolerances than can be obtained by extr
33、usion. Wire, rod,bar, tubes, and special shaped sections are produced as extrusions. Dimensional tolerances on the variousforms are given in the current issue of ASTM B 107-70.Magnesium alloys produced as extrusions are available in the as-extruded (F) condition. In some alloys anincrease in strengt
34、h is obtained by artificial aging to the extruded and aged (T5) condition. Minimummechanical properties of the SAE extrusion alloys are shown in Table 4.
