摘要
Based on the flow stress data obtained from the isothermal hot compression tests, the processing maps of Ti-6Al-4V alloy were developed based on the instability criteria of Prasad, Malas, and Murty. The validation of the processing maps was achieved by investigating the microstructures of compressed Ti-6Al-4V alloy specimens. The results showed that the power dissipation maps obtained using the criteria of Prasad and Murty exhibited similar distribution, whereas the instability domains obtained by various instability criteria had great differences. Microstructure analysis showed that the instability domains determined by Murty's criterion were more accurate than those determined using other criteria.
