将有、无δ铁素体的P92钢管样在700和750℃分别时效1000,3000和5000 h,采用电子探针-X射线能谱分析(EPMA-EDS)和复相分离技术(MPST)研究了δ铁素体对时效析出M23C6及Laves相体积分数及相成分的影响.结果表明,在时效过程中,δ铁素体的存在促进了M23C6及Laves沿δ铁素体的界面析出,发生聚集与粗化,并为该过程提供Cr,Mo和W;在无δ铁素体的P92钢管样中,不同温度下,M23C6体积分数随时效时间的变化速率不同;在有δ铁素体的P92钢管样中,温度降低促进了Laves体积分数的增加,升高温度则有利于M23C6体积分数的增加.此外,提高时效温度和延长时效时间可促进2种析出相的粗化.
