  • Refractory Alloys - an overview | ScienceDirect Topics

    Refractory and dense materials such as molybdenum, tungsten, and rhenium, are candidates for use in nuclear applications. For nuclear fusion reactor concepts in particular, dense refractory alloys that are resistant to liquid metals and that have good thermal conductivity are essential for efficient heat transfer. Similar requirements are evident in nuclear science applications such as spallation neutron sources.
