Study on tensile and thermal fatigue behaviors of additively manufactured cobalt-based alloys alloying with Al and Ni

The paper explores the effects of Al and Ni on the performances of tensile and thermal fatigue of the additive manufactured cobalt-based alloys. Additions of Al and Ni influence the stacking fault energy, amounts of carbides and oxidation capacity. The 1Al15Ni alloy exhibits the best thermal fatigue resistance and elongation.
