Rolling Textures in Compacts of Copper and Steel

Abstract

This study was undertaken to determine whether differences exist in the rolling textures of materials rolled with and without cladding and whether such differences are affected by bonding the clad and core by hot isostatic pressing (HIP’ing) prior to rolling/ Both steel-clad copper and copper-clad steel were studied, using compacts having nominal volume fractions of core equal to.33 and.50. Unclad core material having the same initial thicnkess as the cores was rolled to similar reductions for comparison with material rolled with cladding. No significant difference in the deformation textures, compared to unclad material, were observed for steel-clad copper. However, for copper-clad steel, a pronounced deformation texture developed in the core at lower total reductions than those required to developed the same degree of texture in unclad material. In these cases, the cladding showed evidence of a shear texture. Prebonding of the compacts by HIP’ing intensified this effect.
