MORPHOLOGY OF (Mn, Fe)S SINGLE CRYSTAL GROWTH IN CAST STEEL
铸钢中(Mn,Fe)S单晶生长形态的研究

The step pattern of single crystal growth and the morphology at equilbriium state 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 state is shown to be tetrakaidecahedron consisted of eight {111} planes and six {100} planes, and is a typical example of the O_h-m3m cubic crystal system.
