VT25U (ВТ25У)
VT25U Titanium Alloy: High-Strength Material for Aerospace and Industrial Applications
VT25U Titanium (ВТ25У) is a high-strength, heat-treatable α+β titanium alloy known for its exceptional performance in high-stress environments. This versatile material is used primarily in aerospace, defense, marine, and high-performance industrial applications. The unique composition of VT25U offers an excellent balance of strength, corrosion resistance, and temperature stability, making it a top choice for demanding applications.
Microstructure & Processing of VT25U
VT25U’s alloying and description as α+β class means the microstructure can be controlled by thermomechanical processing (hot working, solution treatment, perhaps aging) to optimize strength + ductility.
Because of the heavy alloying (Mo, W, Zr) the alloy likely has good hardenability and elevated temperature stability, which is advantageous for thicker sections and sustained service.
Research on composites (VT25U/TiB) indicates that the matrix alloy retains strength at high temperature (500-700 °C) when reinforced, which implies the base alloy has good high‐temperature capability.
