Paper Title:
Constitutive Model and Properties of AMT100 Steel at Thermal Deformation
  Abstract

It had been studied that thermal deformation properties of AerMet100 steel (AMT100) by thermal simulation on Gleeble 3500 Simulator, which the ranges of temperature and strain rates were 900~1100°C and 0.01~10/s. According the experiment data, the parameters of thermal deformation was calculated, in which the activation energy is 261.2KJ/mol. The strain-rate sensitivity coefficient is m=0.0998, and temperature sensitivity coefficient is s=7912. The relationship among peak stress and deformation temperature and strain rate was established. And the ranges of temperature and strain rates were 900~1100°C and 0.01~10/s, and the relative errors of calculation results by the stress-strain model were less than 11.3%.
