Abstract Scope For two-phase titanium alloys, predicting the evolution of texture—both macro and micro—during deformation processing is key to developing highly efficient strategies for colony and microtexture breakdown. This work develops a “open-box” framework linking DEFORM, a commercial finite element model for deformation processing, and the viscoplastic self-consistent (VPSC) model, which predicts texture evolution during plastic deformation. Physical experiments with matched DEFORM simulations are used to validate the link and inform parameterization of the VPSC model. This modular framework includes the capability to select rules for phase transformation kinetics, variant selection, and temperature-dependent slip system strengths. The new framework is then used to investigate the orientation dependence of colony breakdown and the formation of microtexture during rolling and forging.
