What are the primary alloying elements in titanium alloys and their functions?

Aluminum mainly stabilizes the alpha phase and improves high-temperature tensile strength and oxidation resistance. Vanadium stabilizes the beta phase, boosting plasticity and forming performance of alpha-beta alloys. Molybdenum and chromium enhance corrosion resistance and high-temperature creep resistance. Trace silicon and tin refine internal grains to reduce brittleness. Each element adjusts phase composition and microstructure, allowing manufacturers to customize alloy formulas to match specific temperature, load and corrosive working conditions.
