1) grain-boundary coarsening
晶界粗化
1.
The results showed that the black reticular grain boundary was formed with 25Cr2Mo1V steel under long-term elevated temperature service,and the grain-boundary coarsening and grain-boundary segregation of V and S contributed to the reduction of impact ductility and caused embrittlement,which resulted in the shortening of its service time.
结果表明:25Cr2Mo1V钢在长期高温下服役会形成黑色网状晶界,且晶界粗化及V、S元素在晶界处的偏聚,导致冲击韧性降低,产生脆化现象,造成其服役时间缩短。
