High-strength, high-ductility aluminum alloy

A process for producing a shaped article, comprising: preparing a first powder having high strength and rigidity after completion of forming, and a second powder having abrasion resistance and surface hardness after completion of forming; compacting those powders to provide a forming material comprising a base part comprising the first powder and a supplemental part comprising the second powder; and forming the forming material into a shaped article by plastic processing, thereby producing a shaped article in which the base part and the supplemental part have different characteristics. The first powder preferably comprises a rapidly-solidified alloy powder and the second powder preferably comprises at least one member selected from among Al,O,, Si,N,, BN, SiC, Al,C,, Al,B,O,and B,O or a mixture of the member and the first powder which may be the same one actually used as the first powder or another one having a different compositions from that of the actually used first powder. The resultant shaped alloy material has an advantageous combination of plural excellent properties, such as high strength and abrasion resistance.
