多元合金元素对高铬白口铸铁铸态组织和性能的影响

The Effect of Multi elements on the Microstructure and Properties of Chromium White Cast Iron As Cast

本文研究了多元合金对高铬白口铸铁铸态组织和性能的影响。试验结果表明:Mo、V、Ti、Cu等合金元素以一定的比例配合使用,有效地改变了基体组织,改善了共晶碳化物的形貌与分布,并显著提高了其铸态冲击韧性和耐磨性。

The effect of multi element alloying on the microstructure and properties as cast of high chromium white cast iron has been studed.It was concluded that alloying with appropriate contents of Mo V Ti Cu changed the matrix microstrucure effectively,and that improved the morphology and distribution of eutectic carbide,and that increased evidently the impact toughness and abrasive resistance as cast.
