摘要
通过重热模拟和透射电镜试验,研究了3种不同含Cu量的9%Cr耐热钢焊缝金属的微观组织结构。结果表明,Cu元素能抑制铁素体的形成,提高钢的强度和抗腐蚀性,强化焊缝组织。
The paper studied three 9%Cr heat-resistant weld metals with different account of Cu with re-heating simulation and transmission electron microscopy experiment.It showed that Cu could limit the account of ferrite,improve the strength and anti-corrosion of steel and strengthen ferrite.
