TEXTURE DEVELOPMENT IN A1 1.8WT-PERCENT-CU DEPENDING ON THE PRECIPITATION STATE .1. ROLLING TEXTURES

The development of a rolling texture and structure in the alloy Al 1.8wt% Cu was analyzed as a function of the precipitation state, which was extensively varied by systematically varying the annealing treatment. While the type of texture (copper-type texture) was independent of the precipitation state, by means of quantitative analysis of the orientation distribution function significant differences in the texture development were revealed, from which conclusions about the differences in the deformation modes for different precipitation states could be drawn.
