Abstract

Abstract

The formation and stability of the intermediate phases of Mn4Si have been investigated by the method of quenching in fusing state under high static pressure (MQFSHP). The results show that (Mn4Si) phase , which is the main part in the Mn4Si alloy smelted in vacuum furnace is unstable; (Mn4Si) R phase, which is not in the Mn4Si alloy smelted in vacuum, is observed by quenching from fusing state under high pressure. The dodecagonal quasicrystal has been found in Mn4Si system by MQFSHP for the first time. The structure and stability of intermediate phases and dodecagonal quasicrystal were analyzed by using X-ray diffraction, electron diffraction and DTA techniques.
