title = "Superelastic response of low-modulus porous beta-type Ti-35Nb-2Ta-3Zr alloy fabricated by laser powder bed fusion",
abstract = "This work investigated the superelastic response of the low-modulus porous β type Ti-35Nb-2Ta-3Zr scaffolds with different pore dimensions fabricated by laser powder bed fusion. The superelastic behavior was enhanced with increasing the pore size and stress-induced phase transformation, which correspondingly led to stress-induced α{"} [110]-type I twin martensitic transformation and ω formation adjacent to β matrix/twins. The resultant interstitial compound phase structure facilitated the β → α{"} and β → ω transition, which was triggered by interfacial stress/strain concentration and high-density dislocations. Substantial high-angle grain boundaries (HAGBs) accumulated high-intensity Schimd factor and crystallographic texture after being deformed. Moreover, a lower Young's modulus was obtained when the pore size and stress increased.",
