摘要：

Our 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 degrees C. The ODF of the beta phase al 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 we 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.
