本文用SEM 505扫描电镜观察到ZG 25钢铸件皮下显微气孔壁上(Mn,Fe)S单晶生长台阶花样和平衡状态的晶体形态.平衡状态面心立方(Mn,Fe)S单晶是由{111}晶形的八个晶面和{100}晶形的六个晶面组成的十四面体.是O_h—m3m类立方晶系对称图形的典型实例.
In this paper, SEM 505 scanning electron microscopy was observed in the ZG 25 steel castings submicrophore stomatal wall (Mn, Fe) S single crystal growth step pattern and equilibrium state of the crystal morphology of the equilibrium state of face-centered cubic (Mn, Fe) S single crystal is The tetradecahedron composed of the eight crystal planes of the {111} crystal and the six crystal planes of the {100} crystal is a typical example of the symmetrical pattern of O_h-m3m cubic system.
