摘要：
The microstructure heterogeneity of Ti-5Al-5Mo-5V-1Fe-1Cr Ti alloy during isothermal compression was revealed. Firstly, the alloy was fabricated via a consumable vacuum arc-remelting furnace. Then the as-cast ingot was subjected to thermo-mechanical processing and heat treatment. The cylindrical specimens were machined from the heat-treated rods. Isothermal compression tests were conducted subsequently. The two ends of the specimens were not rubbed or polished. Results show that large local deformation zones appear in the specimens after isothermal compression, which may cause crack nucleation in the material in the case of loading. Finally, the microstructure phenomenon was investigated.
