Abstract

Thermo-mechanical fatigue (TMF) test of a wrought Co-Cr-Mo alloy was investigated and Co-based alloy showed superior TMF properties than the control sample of a hot work tool steel. During TMF test, high oxidation resistance and increased hardness were observed in the Co-based alloy in contrast to the low oxidation resistance and decreased hardness in the tool steel. The γ-phase-to-ε-phase transformation of the Co-based alloy was considered as the main hardening factor during the TMF test.
