In order to clarify the reaction process of bulk MgB 2 phase, Differential Thermal Analysis (DTA), as the main measurement, was used to prepare bulk MgB 2 samples and monitor the sintering reaction process. Combined with microstructure observation by SEM and X-ray diffraction analysis, the formation process of MgB 2 phase was summarized. The reaction between Mg and B powders...
The γ→α phase transformation behaviours of Fe-Co and Fe-Mn alloys were systematically investigated by dilatometry and Differential Thermal Analysis (DTA). Two kinds of transformation kinetics, called normal and abnormal, were recognized for the first time and classified according to the variation of the ferrite formation rate. These transformation characteristics were observed for both isothermally...
