Wire Electric Discharge Machining of P91 Steel: Microstructure and Thermal Modeling Studies

The effect of different cutting parameters used during wire electric discharge machining (WEDM) of P91 steel on the cutting process, microstructure on or under the surface, and the surface finish was examined in this study with a view toward understanding the cutting process fundamentally. The approach used was based on heat transfer modeling and experimental validation of the thermal effects by examining the microstructure and the surface...
