添加铝对退火态高碳铬钢显微组织与性能的影响
Effect of Aluminum Addition on Microstructure and Properties of High Carbon Chromium Steel in Annealed State
摘 要
对添加质量分数4%铝的高碳铬钢进行退火处理，采用光学显微镜、扫描电镜、硬度计等研究其显微组织和性能，并与不含铝高碳铬钢进行对比。结果表明：添加质量分数4%铝后，高碳铬钢的密度为7.33 g·cm-3，比不含铝高碳铬钢的减小了6%，临界相变点提高，两相区温度范围扩大，适宜退火温度提高了100 ℃，硬度高于不含铝高碳铬钢的；不含铝高碳铬钢为过共析钢，添加质量分数4%铝的高碳铬钢为亚共析钢，铝完全固溶于铁素体中，改变了第二相的析出顺序，使铁素体相优先于渗碳体相析出。

Abstract
Microstructure and properties of high carbon chromium steel with 4wt% aluminum after annealing treatment were studied by means of optical microscope, scanning electron microscope and hardness tester, and compared with those of Al-free high carbon chromium steel. The results show that the density of the high carbon chromium steel with 4wt% aluminum was 7.33 g·cm-3 which was reduced by 6% than that of the Al-free high carbon chromium steel, the critical transition points increased, two phase region was expanded, the suitable annealing temperature increased by 100℃, and the hardness was higher than that of the Al-free high carbon chromium steel. The Al-free high carbon chromium steel was a hypereutectoid steel, while the high carbon chromium steel with 4wt% aluminum was a hypoeutectoid steel. Aluminum dissolved in ferrite completely and changed the precipitation sequence of second phases, therefore the ferrite phase was formed before carbide phase.
