残余元素铜在中碳钢中的析出规律
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
以中碳钢为研究对象，调整Mn，S含量，添加0.3%左右的铜作为残余元素，研究铜在钢中的偏析以及在夹杂物上的析出情况。利用扫描电镜及能谱仪研究发现当钢中锰含量从0.008%提高到0.094%时，可以减轻铜沿原奥氏体晶界的偏析程度。锰含量为0.440%时，铜在硫化锰夹杂上的析出比例可以达到94.6%，继续提高锰含量对提高铜的析出比例无益。通过二元匹配度的计算，可以得出，无论Cu在钢中以何种形式存在，MnS夹杂较氧化硅、氧化铝夹杂更适合铜析出，计算结果与实验结果吻合。
