Paper Title:
Thermal Fatigue Mechanism of Welding Deposited Metal of Dies Steels
  Abstract

This paper conducted the outer constraint test of Coffin thermal fatigue and studied the deformation behaviors of microstructure for two kinds of welding deposited metals, they are 3Cr2W8 and HM3. The experimental results show that the thermal fatigue deformation belongs to multiple slip systems and the heterogeneous deformation mainly concentrates around the second phase particles. Moreover, it is found that the cracking initiation relates to the separation between the second phase particles and base body, void and micro-cracking formation.
