Microstructure, Strain Recovery Characteristics and Corrosion Resistance of Ti–V– Al– Zr Lightweight Shape Memory Alloy
The effect of Zr content on the microstructure, martensitic transformation temperatures, mechanical properties, strain recovery characteristics, and corrosion resistance of the alloys of the Ti – 11V – 9.7Al – xZr system were investigated. It was revealed that with the addition of Zr, the structure of the alloy is gradually transforms from the α″-phase to the β-phase. The addition of Zr decreases the martensitic transformation temperatures of the Ti – 11V – 9.7Al – xZr alloy and significantly improves its yield strength and ductility. The full recovery of 6% strain is achieved in the Ti – 11V – 9.7Al – 5Zr alloy, which shows a high shape memory effect and superelasticity. When the content of Zr reaches 10 at.%, there is no shape memory effect reply. Electrochemical testing revealed that the Ti – 11V – 9.7Al – 5Zr alloy exhibits the best corrosion resistance, and a small amount of Zr addition enhances the corrosion resistance of the alloy.
