dc.description.abstract	A1-5 vol% graphite particulate composite was subjected to equal channel angular pressing (ECAP) at room temperature up to four passes. A significant grain refinement, down to the submicron level of similar to 300 nm was achieved. Hardness enhancement of more than two fold was observed with only a marginal difference along the perpendicular and parallel directions of pressing. Further, the strength of the composites was increased by more than two folds. ECAP at room temperature has resulted in a more rapid and significant grain refinement and strengthening in A1-graphite composite.	en_US
