Advanced Microtexture Analysis of a Ti10−2−3 product: for a Better Understanding of Local Variations in Mechanical Behavio

Ti 10-2-3 parts for high strength application are classically obtained by a complex transformation process including β forging and further α/β forging before aging. The expected microstructure is typically composed of primary αP nodules embedded in a matrix of residual pr and as platelets. In this contribution, in depth microtexture analysis using EBSD and advanced data processing with Merengue 2 software have been performed at different scales ranging from millimeter down to sub-micron. Our goal was to reconstruct the prior high temperature αp/β microtexture and to quantify remaining traces of orientation relationship between αp and β phases as well as β to αs variant selection. New insights of the inherited microstructure are revealed and may explain why local configurations supposed to be similar from microstructural observations could exhibit different mechanical behavior.
