title = "Reaction synthesis mechanism of TiAl alloy fabricated by hot pressed sintering with mixed powders of TiH2 and aluminum",
abstract = "Ti-47Al(at.\%) alloys were fabricated through hot pressed sintering using mixed powders of TiH2 and Al and mixed powders of Ti and Al, respectively, as starting materials. The microstructure of alloys were analysed by differencial thermal analysis (DTA),scanning electron microscopy (SEM) and X-ray diffraction (XRD), and the mechanism of the sintering process were studied. Through the experiment it is found that TiH2 powders have been decomposed to Ti and H2 completely before they react with Al powders during the hot press synthesis. The reaction of TiH2 and Al powders is faster than that of Ti and Al powders during the process of hot press synthesis because Ti formed from the decomposition of TiH2 powder has higher activity.",
