锅炉用钢中碳化物的结构和数量

The Structure and Quantity of Carbides of Boiler Steel 12Cr2MoWVTiB During Service

    摘要
  • 摘要: 采用X-线相分析方法测定了电站锅炉用钢12Cr2MoWVTiB(102钢)在使用过程中碳化结构和数量的变化。结果是,MC型碳化物的数量基本保持不变。M23C6和M6C型碳化物在使用初期数量增加,至8×104以后,数量的变化趋于稳定。

     

    Abstract: By using X-ray phase analysis method, the structure and quantity change of carbides of power plant boiler steel 12Cr2MoWVTiB (Steel 102) during service were determined. The quantity of carbide MC remained basically unchanged during service. The M23C6 and M6C contents increased during the first stage of service, and then gradually grew stable after 8×104 h of service.
