چکیده انگلیسی
Discontinuous yielding behavior of TC11 alloy was found during hot compression tests at temperatures of 1000-1050 °C and the strain rate of 10 sâ1. The flow stress showed a rapid drop and subsequent oscillation after peak stress before true strain of 0.15. It was proved to be the result of the stress induced phase transformation (αâβ), which introduced softening effect for the generation of new β phase. Moreover, the magnitude of the stress drop increased with the increasing of the fraction of stress induced phase transformation. In addition, these newly generated β phase were further deformed by subsequent compression strain. As a result, the phase transformation of βâαⳠwas found in final quenched microstructures.
