Deformation Behaviors of an Additive-Manufactured Ni32Co30Cr10Fe10Al18 Eutectic High Entropy Alloy at Ambient and Elevated Temperatures
文献摘要：
Eutectic high-entropy alloys(EHEAs)that have superior formability are attractive for direct laser deposition technology.In this study,a regular-shaped bulk Ni32Co30Cr10Fe10Al18 EHEA without apparent pores and micro-cracks was successfully fabricated by direct laser deposition.The as-deposited alloy showed a high tensile strength of 1.3 GPa with a ductility of 35％at ambient temperature and a tensile strength of 320 MPa at 760℃.The deformation mechanisms of the as-deposited alloy at ambient and elevated temperatures were investigated by coupling the in-situ tensile test with a scanning electron microscope.It is revealed that the excellent combination of strength and ductility originated from the synergic effects of the FCC and B2 phases in eutectic lamellae.And the generation of cracks along phase boundaries restricted its high-temperature strength above 760℃.
