Abstract
- Isothermal constant strain rate compression experiments were conducted on 34CrNi3MoV steel using a thermal simulation experimental machine to study its thermal deformation behavior, with deformation temperatures ranging from 800 - 1 200 °C and strain rates ranging from 0,01 - 10 s-1 , and the corresponding stress-strain curves were obtained for 60 % compression. According to the results, through regression analysis of the 1stOpt software, parameter values of three constitutive models were obtained, and then the precision of prediction was compared by different models of flow stress.
