Thermomechanical Strengthening of F.C.C. Metals.

Abstract

Aluminum alloys are structurally unstable from both a thermal and a stress activated process point of view. The strain induced structural instability is significant as shown by deformation pole figure work and work hardening curves. This strain induced structural instability can be described as a change in disposition of solute with change in the degree of strain. This effect is most significant in alloys of aluminum and is generally overlooked. Careful control of the structural instability of aluminum alloys allows significant increases in mechanical properties to be achieved. Alloying additions of appropriate solutes also affect the degree of strain induced dispositional change that occurs in aluminum alloys and allow significant increases in the work hardening characteristics of these alloys to be obtained.
