摘要为了研究马氏体板条宽度和显微硬度随奥氏体化温度和保温时间的变化规律，采用扫描电镜（SEM）分析了中国低活化马氏体钢（CLAM）_（HEAT 0603A）经不同热处理后的显微组织，得到了马氏体板条宽度。此外，显微硬度通过维氏硬度测试获得。在此基础上，给出了显微硬度与热处理的关系。综合考虑各因素，CLAM（HEAT_0603A）的最佳热处理条件为1253K × 30min淬火。进一步的研究和调查，如一系列验证测试等，将在不久的将来进行。
Abstract In order to investigate the effect of austenitizing temperature and holding time on the martensitic lath width and microhardness, the microstructures of China Low Activation Martensitic (CLAM) steel_(HEAT 0603A) specimens with different heat treatments were analyzed by scanning electron microscope (SEM), and the martensitic lath widths were gained. Besides, the microhardness was obtained by Vickers hardness tests. Based on these results, the relationship between microhardness and heat treatment was given. Taking all factors into consideration, quenching at 1253K for 30min was the optimum heat treatment condition for CLAM (HEAT_0603A). Further study and investigation, such as a series of verification tests etc., will be carried out in the near future.
