珠光体耐热钢在高温高压及复杂应力作用下，长时间运行后，热强性能下降，碳化物相的成分、大小、形态、分布发生变化。碳化物相的成分变化是指合金元素由固溶体向碳化物相的转移。本文仅就10CrMo910钢主蒸汽管碳化物相成份随运行时间的变化做一论述。曾有资料介绍：对于珠光体
Under the action of high temperature, high pressure and complex stress, pearlite heat-resisting steel decreases in hot-tempera-ture performance after long-time operation, and the composition, size, shape and distribution of carbide phase change. Changes in the composition of the carbide phase refers to the alloying elements from solid solution to the carbide phase of the transfer. This article only 10CrMo910 main steam pipe carbide phase composition changes with the running time to make a discussion. Have information: For pearlite
