Part I:The objective of the present work is to simulate a hot compression test of Ti-6Al-4V to make comparisons with results obtained by real tests (so called Lankford test) in order to evaluate the influence of texture in the anisotropy of the alloy, which may produce a wrong workability of the final rolled productsPart II:The present report is focused on showing the results of the texture prediction of the high-temperature  phase from which the low-temperature  phase came from; and the results obtained with viscoplastic self-consistent (VPSC) model to simulate the compression of the TA6V samplesPart III:This report is focused on two major objectives: the first one is to show the results of the VPSC+Forge calculations and the other is to make an analysis of the work done during the six months it lasted and get some conclusions.The VPSC+Forge simulations consist in the hot compression of cylindrical samples of TA6V alloy where the presence of texture is an important factor in the final oval shape of the sample. The temperature of the test is 880ºC, which means that two phases () are present. The textures are experimental for  phase, and simulated, or predicted, for  phase.
