ENHANCEMENT OF MECHANICAL PROPERTIES AND GRAIN REFINEMENT IN ECAP 6/4 BRASS

K.H. Song, H.S. Kim and W.Y. Kim

Abstract

This study evaluated the grain refinement and mechanical properties of 6/4 brass processed by equal channel angular pressing (ECAP). Increased passes in ECAP led to notable grain refinement, from 13 µm in the initial sample to 300 nm after 4 passes. Grain refinement enhances mechanical properties, such as Vickers microhardness and tensile strength.
