Abstract

By mixing elements with favourable nuclear activation properties to create high
entropy alloys, it may be possible to create a material that can withstand a nu
clear fusion environment while minimising the radioactive waste produced. Such
a material could be used in the extreme thermal and irradiation conditions of
a fusion blanket. A suite of previously unexplored V-Cr-Mn and V-Cr-Mn-Ti
alloys have been fabricated then homogenised and the resultant microstructures
and phases were characterised. Results demonstrate that single-phase body cen
tred cubic solid solution microstructures can be formed in highly-concentrated
alloys incorporating low-activation elements, which is promising for a fusion
alloy development standpoint.
