Abstract
Hot deformation tests of an upward continuous cast Cu–0.19Cr–0.1Ag were performed on a thermal simulation testing machine with various strain rates (0.01–10 s−1) at different deformation temperatures (750–950 °C) to investigate the microstructural evolution of hot deformation and the softening mechanism. From the results, a flow stress reduction ratio diagram was constructed. The diagram was divided into four regions with different softening mechanisms according to the stress–strain curve. Dynamic recrystallization was accompanied by two nucleation mechanisms: continuous dynamic recrystallization (CDRX) and discontinuous dynamic recrystallization, and the effect of CDRX decreased with increasing strain rate.
