Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving
the ductility of tungsten can have significant impact on both the manufacturing of and the
range of applications of tungsten. Although there has been a significant volume of reported
research on improving the ductility of tungsten over the span of several decades, it remains
a difficult challenge. This is at least partially attributable to the fact that the understanding on …
