碳含量对白口铸铁碳化物形貌的影响

Influence of Carbon Content on Morphology of Carbide of White Cast Iron

探讨了碳含量对低合金白口铸铁中碳化物形貌的影响，结果表明，控制碳含量在 2 2％～ 2 6％范围，有利于使白口铸铁中的碳化物在稀土复合变质处理后球团化。

The influence of carbon equivalent on the morphology of carbide of low － alloying white irons was investigated and discussed.The result showed that ke eping carbon content in the range of 2.2％～ 2.6％ was of benefit to promote the carbide of white iron to spheroidize after treating with rare earth.
