透射电镜对40CrMnSiMoV 钢310℃等温下贝氏体转变时碳化物析出过程的形态和晶体学研究表明,该钢在一定转变条件时下贝氏体组织中可同时出现三种不同取向和分布位置的碳化物,它们分别析自奥氏体和贝氏体铁索体。此结果仅为贝氏体按切变机制转变时,方能得到很好理解。
Transmission electron microscopy of 40CrMnSiMoV steel at 310 ℃ isothermal bainite transformation of carbide precipitation process of morphology and crystallography studies have shown that the steel under the conditions of transformation of bainite can occur at the same time three different orientation and distribution of carbonization They were analyzed from austenite and bainitic ferrite. This result is only a bainitic transformation by the shear mechanism, can only be well understood.
