【摘要】 对高铬白口铸铁进行了孕育处理,探讨了高铬白口铸铁组织中碳化物形态的变化特征。研究结果表明:通过孕育处理,高铬白口铸铁中的一次碳化物形貌有明显改善,碳化物形貌为棒状,组织得到明显细化,表明该处理方法对高铬白口铸铁组织具有一定程度的改性作用。更多还原

【Abstract】 The high chromium white cast irons was modifing treated,and the characteristics of carbides were studied.The results show that the morphology of carbides in high chromium cast irons improve visibly,the carbides change to rods and the microstructure become fined apparently,which implies that the modification has somewhat influence on the microstructure of high chromium cast irons.更多还原
