| Outline of Final Research Achievements |
Gradient functional aluminum and Al-Mg alloys were newly produced by means of the heat treatment in the liquid bismuth or indium. The deformation performance at high temperature were affected by the heat treatment caused by the grain boundary diffusion of bismuth atoms. In the high temperature testing, flow stress was decreased, and the ductility were increased. The effect on the deformation is more prominent in the case of Al-Mg alloys, rather than that of pure aluminum.
