Evaluation of Fatigue Strength of Heat Treated and Laser

Laser surface hardening is an advanced method of surface treatment of structural steels with a great potential for wide industrial applications.According to the recent literature results and knowledge about laser hardening,fatigue resistance can be either reduced or increased,even considerably,depending on numerous parameters of basic material,the technology parameters etc.Effect of laser surface remelting on the fatigue crack Mar 01,2019 PDF Fatigue Strength of Laser Hardened 42CrMo4 Steel#0183;In the present work,quenched and tempered 40Cr steel was treated by laser surface remelting,followed by microstructure evolution,hardness,residual stress field and external morphology investigation to understand the effect of laser surface remelting on surface characteristics,as well as the grain refinement mechanism.Effect of Laser Quenching on Microstructure and Properties When the laser power is 1000W,the depth of hardened layer reaches 0.8mm,and the wear resistance of hardened layer increases 167% than that of the substrate.The number,length,and depth of fatigue cracks decreased on the cross-section of worn rails after laser quenching,which indicates that laser quenching can improve the CFR of rails.
