摘　　要：研究了不同的淬火温度对高硼铸钢冲击耐磨性的影响。结果表明,淬火热处理组织为高韧性低碳马氏体基体+高硬度共晶硼化物相。本实验条件下,淬火温度为1000℃时获得的组织具有最佳冲击耐磨性。The Influence of quenching temperature on wear resistance of high boron casting steel was investigated. The results show that heat treating structure is high-tenacity low-carbon martensitic matrix and high-hardness eutectic boride. Under the experiment conditions, 1000℃ is the best quenching temperature,and can obtain the maximum of wear resistance.
