Investigation on microstructures and properties of Al1.5CoCrFeMnNi high entropy alloy coating before and after ultrasonic impact treatment

To investigate the effect of plastic deformation with high strain rate on the microstructure and properties of Al1.5CoCrFeMnNi high entropy coating, ultrasonic impact treatment (UIT) was applied on the surfaces of the cladding coatings. According to the results, before and after UIT, the phase composition of Al1.5CoCrFeMnNi cladding coating did not change, remaining FCC and BCC dual-phase structure. Enormous dislocations were produced and...
