This work examines the recrystallization behavior of bulk pure tungsten subjected to severe plastic deformation by Equal Channel Angular Extrusion at low temperature. Grain size, morphology, and orientation are examined as a function of subsequent heat treatment temperature. Four temperature ranges...
