Development of a Flow Localization Band and Texture in a Forged Near-α Titanium Alloy

Abstract

This work investigated crystallographic textures and the features of a flow localization band in a forged Ti6242S billet. The flow localization band experienced a large strain and grains within it were elongated under shear stress. The main macrotextural components were made up of (11 2 ¯ 0)/<10 2 ¯ 0>, <0002>/axial direction, and a static recrystallization texture (11 2 ¯ 0)/(3 3 ¯ 02), which can be explained by motion of a prismatic <a> slip system and a newly proposed method of projection. Finally, three types of macrozone, each with a sharp defined texture were observed and subsequently, it was demonstrated that the formation of macrozones was only connected with parameters of thermomechanical processing and was independent of variants selection.
