摘要:

研究了在1150 ℃高温条件下保温处理后含铜钢的铜偏聚现象。在空气中采用不同保温时间进行实验，保温时间不超过60 min。结果表明，由于Fe的氧化及脱碳引起的渗碳体转变数量的减少，共同促使更多的Cu析出并向钢/氧化皮界面附近晶界偏聚，导致在空气中经高温处理后，钢/氧化皮界面及其附近的晶界中都出现了Cu的富集；经过冷却相转变后，钢/氧化皮界面附近区域钢中的Cu含量低于高温处理前的Cu含量。

关键词 ：含铜钢, 高温处理, 铜偏聚, 脱碳

Abstract：

The Cu segregation in Cu-containing steel was investigated after high temperature treatment at 1150 ℃ in air for different time. It is found that Cu segregation occurred both at the interface oxide scale/steel matrix and at grain boundaries of the sub-surface of the substrate beneath the interface, which was caused by the preferential oxidation of Fe and the decarburization, thereby resulted in the sharply decrease of the cementite content near the steel surface. It also found that the Cu content in the area beneath the interface oxide scale/steel matrix for the heat treated steel is lower than that of the steel before subjecting to heat treatment.

Key words： Cu-containing steel high temperature treatment Cu segregation decarburization
