| Abstract Scope |
In this work, microstructures, superelasticity, texture characteristics of β-type Ti-30Zr-10Nb-xSn (x=0, 2, 3, 4) (at. %) alloys were investigated. It was found that 2Sn, 3Sn and 4Sn alloys consisted of a single β phase while 0Sn alloy consisted of full α″ martensite. Shape memory effect was observed in 0Sn alloy. The superelasticity with a large recovery strain of 5.2% was observed in 2Sn alloy due to the favorable {001}β<110>β recrystallization texture that largely improved the transformation strain. 3Sn and 4Sn alloys did not show superelasticity at room temperature due to their low transformation temperatures. The effect of test temperature on superelastic behavior was also investigated in 2Sn, 3Sn and 4Sn alloys. It was found that the superelastic behavior is largely dependent on the test temperature and Sn content, which is not only associated with the stress-induced martensitic transformation but also the diffusion of oxygen atoms in nanodomains. |
