3307 Grain Refinement and Mechanical Properties for Environmental f.c.c. Sheet Metals

Abstract

A "Super metal" was produced by controlling the grain size for fine grains. This material has high strength and recycling properties. This study investigated the continuous ARB method to obtain fine-grained crystals from A1100 and C1020 specimens, which respectively showed maximum equivalent strains of 4.00 and 3.46 respectively. The relationships between several mechanical properties, crystallographic orientations, and inverse pole figures obtained from SEM-EBSP analyses were investigated experimentally and analytically. Results clearly showed the influence of crystallographic orientation on micro-bending properties.
