Phase evolution and solidification cracking sensibility in laser remelting treatment of the plasma-sprayed CrMnFeCoNi high entropy alloy coating

open access: yesMaterials & Design, 2019
The mechanism of solidification cracking in a laser-remelted bead of a plasma-sprayed CoCrFeMnNi high-entropy alloy coating was revealed. The oriented dendrite growth and phase distribution of the remelted bead were characterized by electron backscatter ...
