不同磁场强度下W6Mo5Cr4V3高速钢的低温回火析出行为
Low-temperature tempering precipitation behavior of W6Mo5Cr4V3 high-speed steel under different magnetic field strengths
摘要
Abstract
Low-temperature tempering tests were conducted on W6Mo5Cr4V3 high-speed steel under different magnetic field strengths,and the precipitated carbides were analyzed using energy spectrum and wave spectrum techniques to explore the influence mechanism of different magnetic field strengths on the low-temperature tempering carbide precipitation behavior of W6Mo5Cr4V3 high-speed steel.The results show that during low-temperature tempering at 200℃,a strong magnetic field significantly affected the precipitation morphology of M6C carbides,and exhibited strong spheroidization and grain refinement effects.As the magnetic field strength increased,the spheroidization effect showed a gradually increasing trend,and the average size of carbides gradually decreased.Applying a strong magnetic field significantly increased the precipitation amount of M6C and MC type carbides,while significantly reducing the precipitation amount of M2C type carbides.Applying a magnetic field during tempering could improve the uneven distribution of carbides in high-speed steel,and provided a feasible approach to enhance the quality of high-speed steel.关键词
