Microhardnessofthecladalloyinglayerwillbeabout500HV. KeyWorks: lasercladding; Fe3A1; intermetalliccompound5 Conclusion Thermo-calc calculation software design 4Cr5MO3SiVNb steel with high strength and good toughness, the tensile strength of 1660MPa about cross-section shrinkage rate of 50%. While its small and homogeneous, tempering stability, tempering at 650 ~ C hardness remained at around 45HRC. In addition to the performance of such modules is also very good. Based on the results of the heat treatment process can be developed better control the type of steel and carbide morphology to further improve the mechanical properties of materials. For the thermal fatigue of new steel grades I can and high temperature oxidation of Health and other aspects of performance will be reported.
