珠光体

After the vanadium content in PD3 steel was more than 0.33%, vanadium carbides would precipitate a lot, and make the lamellar gap sizes of pearlite abnormally coarsen, it was beneficial to toughness of material.

当PD3钢中钒含量增加到0.33%时，碳化钒将大量析出，并使珠光体片间距反常粗化，对韧性不利。

The microstructure changes of pearlitic eutectoid steel induced by cold rolling were investigated by using SEM, TEM and XRD etc.

Fining pearlite, therefore, is one of the most effective method to further improve the contact fatigue properties of PD3 rail steel.

因此，细化珠光体是进一步提高接触疲劳抗力的有效途径。

In ECAP route C, in order to accommodate the severe shear deformation the deformation form of lamellae cementite in pearlitic steel include periodical bending, periodical shearing and shearing fracture etc .

在C方式ECAP变形中，珠光体钢65Mn中的渗碳体以周期性的弯曲变形，周期性的剪切变形，剪切断裂等形式协调ECAP的强烈塑性变形。

If the deformation of pearlitic cementite is assumed to be purely elastic, the pearlitic colony will become rapidly shaked down plastically.

若假设渗碳体的变形为纯弹性，珠光体团将迅速实现塑性安定。

Ferritic irons have a considerably steeper permeability curve than pearlitic irons .
