Some Aspects of Elevated-Temperature Deformation of Single-Phase Alloys

Abstract

Some critical discussions on creep behavior and deformation mechanisms of single-phase metallic materials are presented. Subjects dealt with are deformation mechanism diagrams and strain-hardening and recovery rates in pure metals, effects of solute atoms (the Cottrell atmosphere and the Suzuki atmosphere) and their limitation in disordered solid solution alloys, and creep characteristics and the strength of single phase materials and two-phase mixture of Ti-Al intermetallics.
