摘要
高速钢中初生ＭＣ碳化物从液相中的析出温度是决定初生ＭＣ碳化物尺寸的主要因素。本文采用冶金热力学估算了合金元素Ｓｉ、Ａｌ、Ｗ、Ｍｏ等对初生ＭＣ碳化物析出温度的影响，提出了相应的计算机程序。结果表明，Ｓｉ和Ａｌ提高通用高速钢中ＭＣ碳化物的析出温度，而Ｗ、Ｍｏ等对ＭＣ碳化物析出温度影响不大。理论估算和实验结果相吻合。
Effects of alloying elements on the precipitation temperature of the primary MC carbide during solidification of high speed steels are evaluated by thermodynamic calculation. This evaluation is quite necessary for development of newtype high speed steels. The computer program is presented for the abovementioned evaluation, which can be used to predict the effects of alloying elements on the primary MC carbide. The calculated results show that the precipitation temperature of the primary MC carbide in commercial high speed steels is increased by the additions of silicon and aluminum, instead of by tungsten and molybdenum. There is a good agreement between the calculated and experimental values.
