Abstract：

Abstract　High-pressure　torsion　(HPT)　and　thermal　annealing　were　applied　to　a　face-centered　cubic　as-cast　Al0.3CoCrFeNi　high　entropy　alloy.　Processing　by　HPT　produced　a　nanostructure　with　a　higher　incremental　hardness　than　in　most　HPT　single-phase　materials　and　subsequent　annealing　at　appropriate　temperatures　gave　an　ordered　body-centered　cubic　secondary　phase　with　an　additional　increase　in　hardness.　The　highest　hardness　after　HPT　and　annealing　was　approximately　four　times　higher　than　for　the　as-cast　alloy.　©　2015　Elsevier　B.V.
