摘要
本文介绍了不同热处理状态下的Ni_9钢显微组织,对Ni_9钢的焊接接头的组织与性能进行了试验研究,并做了初步的理论分析。
The microstructures of 9% Ni steel under various heat - treatment condi-
tions are presented. The experimental studies about the structure and the pro-
perty of the welded joint have been conducted. There is an initial theoretical
analysis in the paper.
