含碳量对高铬白口铸铁组织、硬度及冲击韧性的影响

Influence of Carbon Content on the Microstructure Hardness and Impact Toughness in High Chromium White Cast Iron

进行了合碳量对１６％Ｃｒ白口铸铁组织和性能影响的实验研究，结果表明：随着碳量增加，碳化物的含量增加，并且由连续的网状逐渐变成孤立的花状、杆状和块状；当碳量合适时，硬度和冲击韧性均出现峰值，综合性能最佳。

The investigations were made on the influence of carbon content on ndcrostructure and properties in highchrondum white cast iron. The experimental results indicate that, with the increase in carbon content and thecarbide content, the carbide morphologies is gradually changing from net-work to flower-like, IDd-like and finally toblock type. At the same time, there is a peak value of baldness and impact toughness in carbon content range beingtested.
