Influence of α Precipitation at β/β Grain Boundaries on α Microtexture in a β-Metastable Titanium Alloy with and without Previous Deformation
Abstract
This paper describes the effect of a prior β texture and of variant selection, at a macroscopic scale or locally by using the EBSD technique in titanium alloys. The aim of the present study is to examine how microstructure evolutions (α phase morphology, distribution, formation kinetics), also influence the microtexture development. The effect of a prior deformation in β will be considered, because it strongly influences the heterogeneous α precipitation kinetics and thereby probably the microtexture. Additionally, the purpose of this study is to examine how these microstructure evolutions influence the microtexture development, in the case of α precipitation at β/β GBs, and also highlights the essential effects of α precipitation kinetics will be particularly highlighted.
