Symposium General Poster Session
Presentation Title O-51: Superelastic Scaffolds Prepared by Sintering of Metal Fibers for Biomedical Applications
Author(s) Tae-hyun Nam, Shuanglei Li
On-Site Speaker (Planned) Tae-hyun Nam
Abstract Scope The microstructures and martensitic transformation behaviors of 49Ti-50.3Ni-0.7Ag (at%) alloy fibers were investigated by means of electro probe micronanlyzer (EPMA), differential scanning calorimetry (DSC), X-ray diffraction (XRD). The B2 phase apperas only in the non-heat treated fibers, while Ti2Ni and TiAg phases in addition to the B2 phaser were observed after being annealed. Ti-Ni-Ag alloy fibers annealed at 1073K exhibited excellent superelasticity with a superelastic recovery strain of 2.2% and superelastic recover ratio of 93%. The Ti-Ni-Ag scaffold prepared by sintering the fibers possessed three-dimensional and interconnected pores with a porosity of 80%. The compressive strength of the scaffold was about 5.55 MPa at the strain of 4% similar to that of cancellous bone ranging from 2 to 20 MPa. The elastic modulus was 0.67 GPa, which is also similar to that of cancellous bone ranging from 0.1 to 2 GPa. Superelastic strain of the scaffold observed was 2.52%.
