Özet

The present study includes determination and optimization of parameters which were effective on achieving sub-micron grain size on commercial purity aluminum to be able to use for industrial processes. Equal Channel Angular Pressing (ECAP)-Conform process was attempted at room temperature on commercial purity aluminum wire samples. Number of passes was increased systematically. For characterization purposes, optical microscope, scanning electron microscope, SEM, and transmission electron microscope, TEM, were used. Transmission electron microscopy revealed that sub-micron grain size was attained after 11 passes.
