Abstract
The paper presents highlights of the titanium alloy research developments since Ti-2015 (San Diego). The review underlines the strong and collaborative fundamental research conducted at UK universities through strategic government sponsored programmes. The role of advanced characterisation and modelling techniques in order to better understand the effects of deformation, fatigue loading and environment on titanium alloys continues to be world leading. Researchers in the UK are also continuing to develop a range of new alloys, methods of extraction and emerging near net shape processes via casting, powder and wire-fed routes.

Summary
Over the last 10 years, the £50 million Rolls-Royce / Engineering and Physical Sciences Research Council (EPSRC) Strategic Partnership Flagship Programme in Structural Metallic Systems for Gas Turbine Applications has a clear aim: through fundamental research, to provide the foundation for next-generation aero-engines. A unique feature of this Rolls-Royce / EPSRC Programme was the inclusion of a parallel training programme delivered by an EPSRC Centre for Doctoral Training (CDT). Through this Centre, PhD and EngD students research industry-relevant issues and contribute to the development of engine components destined to enter commercial service. One of the most important EPSRC programmes since Ti-2015 was HexMat (Heterogeneous Mechanics in Hexagonal Alloys across Length and Time Scales). This successful five-year collaborative programme between Imperial College London, Univ. The key Ti industry partners during HexMat were Timet and Rolls-Royce, who are largely responsible for the majority of Ti alloy research in the UK
