A mixture of pure Se and S powders has been subjected to mechanical alloying(MA) at room temperature. Trigonal Se and rhombic S are built up of chain and ring molecules, respectively. Therefore, this process means the mixing of chain and ring molecules. X-ray diffraction patterns during the milling process indicate that the amorphization proceeds with increasing milling time. The amorphous Se-S powders sample shows endothermic and exothermic peaks in the DSC spectrum, which are a glass transition and crystallization respectively. The glass transition temperature decreases with increasing the S concentration. However, the crystallization temperature of the Se-7at%S amorphous sample becomes larger than that of the amorphous Se. This is related to the fact that the Se-7at%S amorphous sample is constructed by the tangled chain and ring molecules.
