摘要
Evolution of the alpha phase precipitation behavior and morphologies characteristics during isothermal deformation of a near beta titanium alloy Ti-7Mo-3Al-3Nb-3Cr (Ti-7333) have been investigated using Transmission Electron Microscope (TEM) and Electron Backscattered Second Diffraction (EBSD). The results indicated that the fine and random alpha phase precipitated during the isothermal deformation. The morphologies of alpha phase precipitation during isothermal deformation are markedly different from those of the alpha phase during heat treatment. The volume fraction of alpha phase increases with the increasing of the true strain. Most of alpha phase precipitates in high-angle grain boundaries (HAGBs) and low-angle grain boundaries (LAGBs), while a small amount of spherical alpha phase precipitates in the grains. The crystallographic orientation of the spheroidal alpha phase is approximate where precipitate most in LAGBs and grains, otherwise different orientation relationship will be presented when the precipitation in grain boundaries (GBs). The alpha phase precipitation during isothermal deformation were affected by amount of dislocations. (C) 2016 Elsevier B.V. All rights reserved.
