Modeling of the texture transformation in a Ti-64 sheet after hot compression

Their aim was to investigate the mechanism of variant selection occurring in the phase transformation of a Ti-64 sheet after compression. For that purpose, a Ti-64 alloy sheet was 38% plastically deformed by compression in the {beta} field at 1050 C. The ODF of the {beta} phase at high temperature was determined by an indirect method. Comparison between the experimental texture of the {alpha} phase at room temperature and a simulated texture calculated without variant selection from the high temperature {beta} texture indicated that the phase transformation by cooling occurred with variant selection. By simulating the texture change due to the {beta}-{alpha} transformation the authors showed that in a first approximation this variant selection can be related to the active slip systems involved in the plastic deformation of the {beta} matrix.
