| Abstract: | The step pattern of single crystal growth and the morphology at equilbriiumstate of (Mn, Fe)S on the wall of micro-voids in ZG25 cast steel have been observed using scan-ning electron microscope. The face-centred cubic (Mn, Fe)S single crystal at equilibrium stateis shown to be tetrakaidecahedron consisted of eight {111} planes and six {100} planes, and isa typical example of the O_h-m3m cubic crystal system. |
