pearlite(【技】铁素体片和渗碳体片交替排列的层状纤维组织，是过冷奥氏体进行共析反应的直接产物。因为这种组织的试样在抛光蚀刻后具有珠母贝的光泽，故由此得名。: In grey cast iron most of the carbon is present as flakes of graphite, and there is usually a remainder which is in the form of pearlite； the fracture of this type is grey. 在灰铸铁中，大部分碳以片状石墨的形式存在，其余的碳通常以珠光体的形式存在，这种类型铸铁的断口呈灰色。)
pearlitic malleable iron(Pearlitic malleable iron can be produced by increasing the amount of manganese in white cast iron and heat-treating it 在白口铸铁中增加锰含量并进行热处理，即可生产出珠光体可锻铸铁。)
