USE OF XRD AND HOLE-DRILLING METHOD FOR DETERMINATION OF RESIDUAL STRESSES GRADIENT IN C45 STEEL AFTER LASER HARDENING
Original language description
Laser hardening is a surface treatment method which is successfully used especially when localized hardening of surface is desired. The correct choice of laser hardening parameters must be verified experimentally because the fundamentals of the process rest in structural changes of the material, namely the phase composition and real structure such as appropriate state of residual stress. X-ray diffraction represents the experimental method that has the capability to give these parameters non-destructively in the thin surface layer. In our study, the focus was to ascertain the effect of laser beam width on the depth distribution of residual stresses. The diffraction approach was thus combined with hole-drilling method. The obtained results from both themethods show that the depth distributions of residual stresses have advantageous hook-like shape with tensile stresses on the surface, gradually decreasing to compressive stresses in the depth of approximately 0.3 mm beneath the surface.
