Performance of two different constitutive models and microstructural evolution of GH4169 superalloy

Mathematical Biosciences and Engineering, 2019
The hot compression tests of GH4169 superalloy were performed in the deformation temperature range of 970 to 1150 ℃ and at the strain rate range of 0.001 to 10 s−1. The flow stress is dependent on temperature and strain rate.
