YG8 cemented carbide samples were treated with pulsed magnetic fields having different magnetic field intensity(0.5 T,1.0 T and 1.5 T),and the effects of pulsed magnetic fields on the microstructure, mechanical properties and tool cutting performance of the cemented carbide were studied.The results show that as the intensity of the pulsed magnetic field increases, both the hardness and transverse fracture strength of the cemented carbide samples gradually increase, and the cutting performance of the cemented carbide tools also gradually improves.The pulsed magnetic field provides the driving force for the movement of the dislocations in the cemented carbide, which results in easier dislocation multiplication and slippage to form high-density dislocation cells and significantly improve material mechanical properties and tool cutting performance.
