**3. Development of W-based composites for nuclear applications**

Conventional alloys of W exhibit brittle behavior [40]; therefore, the development of W-based composite materials is considered to be advantageous for incorporating W with desirable properties [40]. A number of additives [36, 41–47] have been examined for the production of W composites with enhanced high-temperature mechanical properties [48–50] and good irradiation resistance [51–53].
