Tungsten (W) is a brittle material at room temperature making it very difficult to fabricate.
Although the lack of ductility remains a difficult challenge, nano-sized and ultrafine grain
(UFG) microstructures offer potential for overcoming tungsten's room temperature brittleness.
One way to manufacture UFG W is to compact and sinter nanosized W powder, however, it is
a non-trivial task to control grain growth during sintering. In an effort to inhibit grain growth,
the effect of Ti-based additives on the densification and grain growth of nano-W powders …
