Effects of Ti raw materials on microstructure and properties of W–Ti alloys
Tungsten–titanium alloys were obtained by high-energy ball milling and vacuum hot-pressing sintering, using titanium hydride powders, irregularly shaped Ti powders, and spherical Ti powders as the titanium source, mixing with pure tungsten powders as the raw materials. The phase composition, microst...

| description | Tungsten–titanium alloys were obtained by high-energy ball milling and vacuum hot-pressing sintering, using titanium hydride powders, irregularly shaped Ti powders, and spherical Ti powders as the titanium source, mixing with pure tungsten powders as the raw materials. The phase composition, microstructure, grain size, relative density, and hardness of tungsten–titanium alloy were measured and studied by X-ray diffractometer, scanning electron microscope, and Vickers hardness tester. The results show that the black titanium-rich phases (β1(Ti,W)) are observed to be distributed in the gray tungsten-rich phases (β2(Ti,W)) of the tungsten–titanium alloys using the three titanium source. The relative density of all these samples exceeds 99%, meeting the compactness requirements for the conventional high-performance target materials. Due to the physicochemical difference of the titanium source, the distribution and particle size of β1(Ti,W) in the tungsten–titanium alloys are different. The tungsten–titanium alloys prepared with TiH2 powders as the titanium source show the best performance. The β1(Ti,W) distribution is uniform, and the grain size is fine; the mutual diffusion rate between tungsten and titanium is higher, and the solid solubility is higher; the relative density and mechanical properties are the best, the relative density is 99.66%, and the hardness is HV (678.88±15.25). |
