Microstructural, mechanical and electrochemical properties of AlCrFeCuNiWx high entropy alloys

Microstructural, mechanical and electrochemical properties of AlCrFeCuNiWx high entropy alloys

AlCrFeNiCuWx high entropy alloys were fabricated on 316 L stainless steel substrate using laser metal deposition technique. The microstructural and mechanical characteristics of these alloys were studied by advanced characterization techniques. The results revealed that the alloys exhibited a dual p...
