Study on Microstructure and Mechanical Properties of WC-10CoCrFeMnNi High-Entropy Cemented Carbide AITranslate
Abstract AITranslate
CoCrFeMnNi high-entropy alloy powder with equal molar ratio was prepared by mechanical alloying,and WC-10CoCrFeMnNi cemented carbide was prepared by spark plasma sintering.The microstructure and properties of high-entropy alloy powder and cemented carbide were studied by X-ray diffractometer,scanning electron microscope,energy dispersive spectrometer,Vickers hardness tester,and laser particle size analyzer.The results show that the nanocrystalline CoCrFeMnNi high-entropy alloy powder,with BCC as the main phase and FCC as the secondary phase,can be obtained by 80 h of ball milling.The ave-rage particle size is 1.4μm,and the particle size distribution is relatively centralized.The cemented carbide,using CoCrFeMnNi high-entropy alloy as the binder phase,exhibits excellent mechanical properties.And the cemented carbide sintered at 1250℃has better comprehensive mechanical properties,with a Vickers hardness of(1452±18.95)HV30and a fracture toughness of(8.57±0.32)MPa·m1/2.
