- Abstract
- Highly porous Ti-Zr-Nb-Sn scaffolds were prepared by sintering of rapidly solidified alloy fibers. Clear superelastic behavior was observed in as-spun alloy fibers at temperatures between 153 K and 298 K. The scaffolds showed three-dimensional networks with fiber-fiber bonds, whose porosity and pore size are about 80% and larger than 150 ?m, respectively. The compressive yield stress and elastic modulus of scaffold annealed at 973 K for 1.8 ks are about 4.0 MPa and 0.3 GPa, respectively, similar to that of cancellous bone. Recoverable strain of 4.0% was observed in the scaffold at room temperature. ? 2019 MS&T19®
