利用透射电子显微镜对12T 强磁场条件下中碳低合金钢在高温700℃和中温530℃等温反应时碳化物在铁素体中的析出行为进行了研究.结果表明:在高温700℃等温时碳化物的析出顺序没有改变;但在中温530℃等温时碳化物的析出顺序发生改变.
The carbide precipitation in ferrite during ioothermal holding at 700℃ and 530℃ in a medium carbon low alloy steel was investigated under a 12 Tesla high magnetic field utilizing transmission electron microscopy (TEM). Results show that the sequence of carbide precipitation at 700℃ is not changed; and conversely the sequence of carbide precipitation at 530℃ is changed.
