摘要
对经长时间运行的T91与G102异种钢焊接接头的显微组织进行了试验分析,结果表明,经7.8×104h运行后,T91母材的显微组织没有发生明显的变化,G102母材的显微组织发生了回复和再结晶转变,可能导致蠕变性能变差。
Test analysis is made for microstructure of T91/G102 dissimilar steel welding joints having been worked long time.The results after operation of 7.8×104 h show that microstructure of T91 steel has not changed obviously,but G102 steel's microstructure restored and mined,and leading crawling characteristics to become bad.
