含铜钢

试验表明：含铜钢（0.025&0.28%Cu）经高温氧化后，其表面氧化铁皮下会产生局部Cu-Ni-As元素的富集（或富集相）。

The experiment shows : the surface of copper-containing steel ( 0.025-0.28 % Cu ) under skin of iron oxide will produce enrichment of Cu-Ni-As element ( or phase of enrichment ) partially after being oxidized by the high temperature .

研究发现，无Ni含铜钢在1100~1200℃会形成液态富铜相，并向奥氏体晶界渗透，成为表面裂纹源。

The results showed that copper enriched liquid phase is formed at reheating temperature of 1 100 ~ 1 200 ℃, and the liquid Cu enriched phase is penetrated along austenite grain boundary leading to surface cracking .
