Non-classical homogeneous precipitation mediated by compositional fluctuations in titanium alloys

TL;DR: In this article, the authors investigated the origin of the deleterious grain boundary α phase formed during the aging of the β-titanium alloy, Ti-5Al-5Mo-5V-3Cr 0.5Fe (wt.%).

TL;DR: Researchers employ phase field simulations to design heterogeneous precipitate microstructures in β-Ti alloys by manipulating cooling rates, achieving exceptional mechanical properties, including 1260 MPa ultimate strength and 14% total elongation, through controlled phase transition mechanisms.

TL;DR: In this paper, the authors show that the heating rate to the aging temperature is crucial in determining the extent of continuous grain boundary formation in aging hardened metastable β titanium alloys.

TL;DR: The Materials Properties Handbook: Titanium Alloys as discussed by the authors provides a data base for information on titanium and its alloys, and the selection of specific alloys for specific applications, including applications, physical properties, corrosion, mechanical properties (including design allowances where available), fatigue, fracture properties, and elevated temperature properties.

TL;DR: This is the first introductory guide to the CALPHAD method, providing a theoretical and practical approach, and the reader will be confident in assessing, optimizing and validating complex thermodynamic systems alongside database construction and manipulation.
