Hot-working mechanisms / H.J. McQueen, Physical Metallurgy Division.: M38-8/74E-PDF

"Before introducing the results of hot-working experiments, the techniques and their limitations are described. Microstructural observations and mechanical measurements are discussed separately. The microstructure of hot-worked single-phase alloys consists of polygonized cells; the degree of polygonization increases with rise in temperature, decrease in strain rate and greater facility of dislocation cross-slip and climb. The mechanism thus appears to be dynamic recovery without recrystallization. Recrystallization in the course of deformation may occur in multi-phase alloys. It is shown that the most suitable empirical expression relating strain rate, temperature and flow stress can be interpreted in terms of a stress-aided, thermally-activated process"--Abstract, p. 379.
