Effect of N addition on nano-domain structure and mechanical properties of a meta-stable Ti-Zr based alloy
Original language description
This study showed that a superior combination of high strength and ultra-low modulus can be achieved by the addition of N in a meta-stable beta-type Ti-Zr based alloy undergoing stress-induced martensitic transformation. A Ti-18Zr-3Nb-2Mo-3Sn alloy exhibited a very low Young's modulus; however, the stress-induced martensitic transformation occurred at a low stress level. The addition of N facilitated the formation of nano-sized lattice modulation (nano-domain) structure and impeded the stress-induced martensitic transformation, leading to higher apparent yield stress, narrower stress hysteresis and large non-linear elasticity. A Ti-18Zr-3Nb-2Mo-3Sn-1.2N alloy exhibited an excellent combination of a low Young's modulus of 41 GPa and a high strength of 920 MP along with a large recovery strain with negligible hysteresis.
