TEXTURE DEVELOPMENT IN DUAL-PHASE ALPHA BETA-BRASS .1. ROLLING TEXTURES/

The development of the rolling texture in two phase alpha/beta-brass C u-40% Zn containing 20 vol.% beta phase was investigated in both phase s by analysis of the 3-dimensional orientation distribution functions. The reliability of X-ray texture data was studied. The texture result s were compared to those of the single phase alloy Cu-37% Zn and to li terature data. It was found that the development of the fcc alpha phas e rolling texture is only slightly influenced by the presence of the b eta phase. In the bcc beta phase weak fibre textures similar to other bcc materials form. The exact texture development could be interpreted by means of Taylor deformation-models with increasingly relaxed const raints. The formation of the recrystallization textures was also deter mined, the results are presented in Part II of this paper.
