利用扫描电镜实验并观察了铸铁轧辊断口中的几何花样。分析确定,铸铁枝晶除沿〈100〉方向长大外,还沿〈110〉方向长大。结晶台阶均属于{100}和{110}晶面。
Scanning electron microscopy experiments were performed to observe the geometric patterns in the fracture of the cast iron roll. Analysis confirmed that cast iron dendrites in addition to growing along the <100> direction, but also along the <110> direction of growth. Crystallization steps belong to {100} and {110} planes.
