The main reasons are the forming of eutectoid structure, the increase of the phase interfaces, the enhance of the plastic deformation resistance, as well as the increase of the hard particles.
这是因为该复合材料中形成了共析组织，且相界面增多，塑性变形抗力增大，硬质点数量增多。
The resulting structure is a mixture of primary or pro-eutectoid ferrite (ferrite that formed above the eutectoid reaction) and regions of pearlite.
作为结果的组织结构是初步的共析铁素体(在共析反应前的铁素体)和部分珠光体的混合物。
