However, copper enrichment around grain boundaries in copper containing steel plate leads to a kind of defect called copperbrittleness.
但是铜在钢中极易在晶界富集，引起铜脆缺陷。
2
Improving the time and temperature of hot-working process rationally, the hot brittleness caused by residual copper is lightened.
合理地改善热加工时间和温度，可以减轻钢中残余铜元素所导致的热脆性。
3
The more the content of residual copper in steel, the more severely the oxidation corrosion occurs on grain boundary and matrix, the greater the hot brittleness tendency;
