Abstract
用电解充氢法研究了微合金化洁净车轮钢产生氢鼓泡的可扩散氢临界质量分数。结果表明，洁净车轮钢的可扩散氢质量分数随充氢电流密度的增加而增加，氢鼓泡密度也随着充氢电流密度的增加而增加，试样中产生氢鼓泡的可扩散氢最低质量分数为2.22×106。设定氢鼓泡密度0.5 cm2≤ρ≤3 cm2为临界条件，则产生氢鼓泡的可扩散氢临界质量分数为(3.64±0.55)×106。

残余元素铜在中碳钢中的析出规律
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0.4...
