Formability and mechanism of pulsed current pretreatment–assisted laser impact microforming

Residual stress reductions of carbide cutting tools through applying pulsed magnetic field and coupled electromagnetic field – mechanism analysis and comparison study

“…Although both electric current treatment [16,17] and magnetic field treatment [18,19] have certain effects on the properties of the materials treated, extent of the effects was limited by applying one kind of the field alone. Liu et al [20] presented an innovative approach to change the cemented carbides' microstructures in order to improve milling and mechanical performances by combining pulsed magnetic and pulsed current fields, and the experimental results demonstrated that the electromagnetic process tended to promote the dislocation density of the cemented carbides, finally strengthening the material property.…”
