ABSTRACT:
A process for producing an aluminum alloy in the form of mass includes: preparing as a material to be formed a mixed powder of aluminum and at least one kind of metal or non-metallic substance selected from the elements belonging to Groups 4a, 4b, 5a, 6a, 7a and 8a of the periodic table and boron, or a compact or a cast material formed of the mixed powder; placing the material to be formed in a die, and performing plastic deformation repeatedly on the material to be formed at 100.degree. to 400.degree. in an inert atmosphere while retaining at least part of the material to be formed in a confined state, so as to cause diffusion reaction between phases constituting the material to be formed, thereby forming the quasi-stable phase composed mainly of amorphous phases and/or supersaturated solid solution phases. The simple plastic deformation alone gives rise to an aluminum alloy which has the quasi-stable phase (such as amorphous phases and supersaturated solid solution phases) and which is in the form of a mass having a shape similar to that of a finished product.
