Effects of TiCl4 purity on the sinterability of Armstrong-processed Ti powder

The sintering behavior of titanium powder produced via the Armstrong process from two different grades of TiCl4 was investigated by a combination of thermal, chemical, and microstructural analysis techniques. It was found that the use of lower grade TiCl4 leads to higher part density due to a difference in sintering behavior that affects the entrapment of volatiles within the sintered body.
