摘要: A predictive model for residual stresses induced in a laser hardened workpiece of AISI 4140 steel with no melting has been developed and experimentally verified. transient three-dimensional thermal kinetic is first solved to obtain the temperature solid phase history workpiece, which then sequentially coupled stress predict stresses. The transformation strains are added at each time step during heating cooling cycles resultant workpiece. importance considering explained through comparison magnitudes without inclusion kinetics. predicted strong compressive about 200 MPa heat affected zone due austenite-to-martensite transformation. predictions matched well X-ray diffraction measurements.
