Severe Plastic Deformed Pure Aluminum by Equal Channel Angular Pressing
Keywords:
Severe Plastic Deformation (SPD), Equal Channel Angular Pressing (ECAP), grain refinement
Abstract
Samples of an aluminum alloy were subjected to an equal channel angular pressing (ECAP) at room temperature for one pass. For the several specimens severe plastic deformation process was interrupted to observe the material flow. Also are studied the force variation in SPD process and hardness in different zones of the deformed sample.
