摘要
以含钛过共晶高铬铸铁为研究对象,分析不同热处理温度下其显微硬度、宏观硬度和冲击韧度的变化规律。结果表明,随着热处理温度的升高,含钛过共晶高铬铸铁显微硬度和宏观硬度均呈现先增加后降低的趋势,热处理温度为1 000℃时出现峰值。另外,和未经热处理的过共晶高铬铸铁相比,含钛过共晶高铬铸铁具有更高的冲击韧度。
The microhardness, macrohardness and impact toughness of hypereutectic high chromium cast iron with titanium were studied under different heat treatment temperatures. The results show that with the increase of heat treatment temperatures, the microhardness and macrohardness of hypereutectic high chromium cast iron with titanium increase first, and then decrease, and the peak temperature is 1 000 ℃. Besides, the impact toughness of hypereutectic high chromium cast iron with titanium are better than ordinary high chromium cast iron.
