TiC粒子增强型耐高温磨损钢设计
Design of TiC reinforced high-temperature wear resistant steel
摘要
Abstract
To develop high-temperature wear resistant steel with high tempering stability that can be used in high temperature environments,the bond energy between different alloying elements and C element is calculated by solid and molecular empirical electron theory,and a series of TiC particle-reinforced high-temperature wear-resistant steel components are designed.The precipitation temperature of TiC particles is calculated by Thermo-Calc software and the tempering stability of the steel plate after the best heat treatment is tested at different temperatures and time.The results show that the bond energy formed by Cr,Mo,and W with C is significantly higher than that of Fe—C.Therefore,the activation energy of C atom diffusion in martensite increases,which hinders the diffusion of C atom in martensite and improves the tempering resistance of martensite.Therefore,Cr,Mo,and W are determined as the main addition elements to improve the thermal stability of TiC-reinforced martensitic wear-resistant steel.TiC particles precipitate in the temperature range of 1400-1500℃,and the particle morphology shows that the particles distribute like grain boundaries.After thermomechanical processing,micron TiC particles can uniformly distribute on the matrix.The experimental results of tempering stability show that the addition of Cr and W elements greatly improves the tempering stability.关键词
