An investigation of mechanical-thermal coupling treatment on material properties, surface roughness, and cutting force of Inconel 718

It is common that Inconel 718 is difficult to cut, which limits its application unavoidably. In this study, the mechanical-thermal coupling (MTC) treatment method is applied to improve the machinability of Inconel 718. After MTC treatment on Inconel 718 surface, the severe plastic deformation is produced easily, and the grain is refined without new substance produced. Moreover, a theoretical and computational model taking account of the electric...
