Effect of magnetic field treatment on microstructure,mechanical properties and wear resistance of YG8 cemented carbide was studied by means of microstructure observation,mechanical properties test,friction and wear test and machining test,and the machining performance of the magnetic field treated cemented carbide tool was evaluated.The results show that after magnetic field treatment,the fracture toughness of the YG8 cemented carbide specimens are improved,the wear resistance is significantly enhanced,and the friction coefficient is reduced.Meanwhile,the surface of the workpiece machined by the cemented carbide tool with magnetic field treatment is smooth and flat,and the overall machining quality is high.Under the action of pulsed magnetic field,magnetoplastic effect will occur in the material,which provides driving force for dislocation movement,and the dislocations are more prone to generate proliferation and slip,the dislocation density increases,so that the mechanical properties of the material are significantly increased,and the wear resistance is improved.
