A Review on High-Strength Titanium Alloys: Microstructure, Strengthening, and Properties

The authors review the recent advances in the development of high-strength titanium alloys. First, they summarize conventional strengthening approaches and their mechanisms, thecorresponding microstructures, and the optimized mechanical properties. Subsequently, various strengthening strategies for high-strength titanium alloys are discussed. Finally, examples of the successful development of high-strength titanium alloys based on amorphous crystallization via solid and semi-solid sintering are presented. The review of the interrelation between the microstructure, the strengthening, and the properties may provide significant insight into achieving novel high-strength titanium alloys.
