中文摘要：

研究了在不同热处理工艺下强磁场对Fe-0.76%C合金冷却转变过程的先共析铁素体显微组织及共析点所对应的碳含量的影响。结果表明：不论在何种工艺条件下施加磁场后Fe-0.76%C合金的先共析铁素体析出量均明显增加,而且共析点所对应的碳含量也随之明显增加。原因被归结为降低了先共析铁素体形核所需驱动力,从而有利于先共析铁素体的形核和长大,使共析点向高碳方向移动。

英文摘要：

The microstructure of proeutectoid ferrite and carbon content at eutectoid point of Fe-0.76%C alloy treated with different heat treatment process without and with applying magnetic field was examined.It is found that the amount of proeutectoid ferrite and the carbon content at eutectoid point increase obviously for the alloy under magnetic field heat treatment.Magnetic field decreases the driving force of nucleation of proeutectoid ferrite and shifts the eutectoid point to the side of high carbon content.
