Thermal shock of subsurface material with plastic flow during scuffing

Abstract The thermal shock of subsurface material with shear instability and severe plastic flow during scuffing was investigated. damage M50 steel tested using a high-speed rolling—sliding contact test rig, the transient temperature calculated Fourier transform method considering effects both frictional heat work. results show that rapid rise subsequent decrease in is generated layers. power intensity generates high rise, leading to austenitization material. Consequently, layer under stress, resulting strain energy further increase. Subsequently, quenches material, clear slip bands retained austenite layers steel.
