Paper Abstract

The possibilities of laser-ultrasonic hardening of surface under checked change of its structural-and-phase composition and residual stresses level were experimentally determined. On high-chromic tool steel in its initial annealed condition it was shown that the harder and deeper zones of surface hardening are formed under the laser-ultrasonic influence. The plastic deformation of surface by the ultrasound influences noticeably the fullness of austenite formation process and hereunder allows to effectively check a strained condition of the surface in the laser influence zone.
