The phase transformation kinetics of pearlite to austenite in low alloy steel was studied by the methods of DSC.

采用DSC法研究了低合金钢组织中珠光体！奥氏体的相变动力学。

The effect of deformation on the phase transformation from pearlite to austenite in low alloy steel was studied by DSC.

采用DSC法研究了变形对低合金钢组织中珠光体！奥氏体相变的影响。

The increase of austenite grain boundaries and crystal defects can increase the nucleation rate of ferrite transformation, but it has no direct effects on the pearlite transformation.

变形造成的奥氏体晶界面积和晶体缺陷的增加只是增加了铁素体相变的形核率，而对珠光体的形核却没有直接的影响。

When the finishing temperature is 950℃ and the cooling rate is 4℃/s, the interlamellar spacings of pearlite is a bout 97 nm and the percentage of sorbite is 95.7%. At this time, the structure is the best.

高碳钢SWRH77B在终轧温度为950℃、冷却速度约为4℃/s时，其珠光体的片层间距约为97nm，索氏体含量达到95.7%左右，表明此时的组织为最佳索氏体组织。

The characteristic of the new process is heating under Acl temperature for suitable time to change lamellar Sorbite to ginger-like Sobite.

工具钢在稍低于Acl温度下不太长时间保温，可使珠光体片不完全球化，形成姜块状索氏体，淬火后得到马氏体＋姜块状碳化物组织。

The effect of heat transfer characteristics on the weldability...

这种传热特性对贝氏体钢轨的焊接性有明显的影响；根据计算及试验结果，贝氏体钢轨的焊接应当采用比珠光体钢轨更小的焊接热输入参数。

Thin laminar pearlitic colony is the element of a kind of two phase materials,which is composed of the thin lamellas of ferrite and cementite one over the other.

细片层珠光体团是由铁素体片和渗碳体片交替叠合而成的复相材料。

However, semi-steel is made of 10 ~ 20% cementite and pearlitic matrix, there exists no pellet-shaped graphite, so sticking is easy to happen to it, which is not expected dunng rolling.

然而半钢材质是由10-20％渗碳体及珠光体基体所组成，其内不存在球状石墨，所以半钢材质容易产生粘钢现象，这是轧制过程所不希望的。

The results show that the cyanided samples have lower A_1 temperatures, considerablyhigher M_s points and shorter incubation periods in both the pearlitic and bainitic regionsthan the carburized samples.

实验结果指出：氰化试样较渗碳试样具有较低的A_1温度、高得多的M_H点、和过冷奥氏体在珠光体与异茵体区间转变时较短的孕育期。

The Ni-based self-fluxing alloy powder coposite coating was produced on the substrate of ferrite and pearite base gray iron by the general electrical resistance furnace with graphite protection successfully.

用普通电阻炉加石墨保护的方法成功地在铁素体基灰铸铁及珠光体基灰铸铁基体上制备了镍基自熔性合金粉末复合材料。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
