摘要

The effects of thermomechanical parameters on the flow stress of Ti60 alloy were investigated based on the results of the isothermal constant strain rate compression tests. The results show that the flow stress of Ti60 alloy reduces with the increasement of temperature and decreasement of strain rate, which presents strong strain rate sensitivity and temperature sensitivity. The constitutive equation of Ti60 alloy was obtained on power function equation and Z-H parameter. The results of error analysis show the relative error between the calculated and experimental flow stress is less than 10%. The constitutive equation can describe the flow behavior of Ti60 alloy during hot-working exactly.
