研究了碳化钨（ＷＣ）增强钢基复合材料在９８０～１２４０℃温度范围的高温奥氏体化行为及相应的淬火硬化效应．发现此材料的奥氏体化温度范围宽，在９８０～１１００℃加热淬火均能得到细小的组织结构，而且具有显著的淬火硬化效果（ＨＲＣ６８）．并且测量及探讨了不同状态下大块硬质相、ＷＣ聚集区及基体显微硬度（ＨＶ０．０５）的变化以及与宏观洛氏硬度之间的关系．
The high temperature austenitizing behavior and corresponding quench hardening effect of WC-reinforced steel matrix composites at 980-1240 ℃ were studied. It has been found that this material has a wide range of austenitization temperature and can be obtained by heating and quenching at 980-1100 ℃. It has a remarkable microstructure and has a quench hardening (HRC68) effect. The relationship between the change of macrohardness, WC agglomeration area and matrix microhardness (HV0.05) and macro-Rockwell hardness under different conditions was also measured and discussed.
