Title:
Texture development during the hot forming and annealing of two phase Ti and Zr alloys.

Abstract:
Texture control is of great importance during the processing of dual phase Ti and Zr alloys, since texture affects their properties and performance in service.
Although we have a good empirical understanding of the texture development during processing, our fundamental understanding of the mechanisms responsible is lacking. We know that deformation, phase transformation and recrystallization are all involved, but there is no consensus on their relative importance and how it changes with changes in processing conditions.

In this talk, I will present results from recent studies on Ti and Zr alloys that aimed to unravel the contribution of these different mechanisms to the texture development in these important alloys.

These studies included lab scale hot working simulations, in-situ synchrotron and EBSD studies, as well as computational experiments using crystal plasticity modelling. The results provide a new insights into this complex process and provide a basis for making improved predictions of texture evolution during the processing of these alloys.

This session was chaired by prof. Leo Kestens (Ghent University).
