Unexpected brass-type texture in rolling of ultrafine-grained copper
, 2014 International audiencePerforming large-strain rolling of initially ultrafine-grained copper obtained by eight passes in equal-channel angular pressing, a brass-type - rather than a copper-type - texture was achieved. Clearly, the deformation mechanism is
