| Abstract | The sintering densification behaviors of Ti-1Al-8V-5Fe alloys by saturated titanium hydride (TiH2) and unsaturated titanium hydride (TiH1.5) powders are investigated. The results show that the TiH2-185 specimens present better sintering densification ability compared with TiH1.5-185 specimens, which displays that the titanium hydride with more hydrogen has a stronger densification ability. The TG-MS analysis suggests that the decompositions of TiH2 and TiH1.5 powders are accompanied by the H2O releasing, and the TiH2 releases more H2O than that of TiH1.5. The twice phase transformations can be observed in the TiH2-185 specimens by DSC, which contribute to the H2O releasing and dislocations and vacancies. Thus, TiH2 powder is helpful to obtain higher sintering densification and better mechanical properties for Ti-1Al-8V-5Fe alloy. |
