| 摘 要： | 分析了铸态及不同热处理工艺条件下高铬白口铸铁的组织和性能，结果表明：高铬白口铸铁铸态组织中共晶碳化物呈宫续和断续网状分布，对材料的韧性损害较大，通过热处理后可改善共晶碳化物的形态及分布，同时使基体组织到强韧化配合。

Effect of heat treatment on microstructure and mechanical properties of high Chromium white cast iron |
| |
| Abstract: | The microstructure and mechanical properties of high Chromium white cast iron after casting and heat treatment are studied. The result shows that the eutectic carbide after casting presents continuous or intermittent net shape, it evidently decreases toughness. After heat treatment, the distribution of eutectic carbide is considerably improved and the microstructure also tends to be improved. |
