Mitsuo Niinomi,Masaaki Nakai +1 more
TL;DR: Effective methods to improve the static and dynamic strength while maintaining low Young's modulus for β-type titanium alloys used in biomedical applications are discussed.
Journal ArticleDOI
Beta type Ti–Mo alloys with changeable Young’s modulus for spinal fixation applications
TL;DR: The microstructures, Young's moduli and tensile properties of the alloys were systemically examined to investigate the effects of deformation-induced ω phase transformation on their mechanical properties and Ti-17Mo alloy is considered to be a potential candidate for the spinal rods in spinal fixation devices.
Journal ArticleDOI
Characterization of air-formed surface oxide film on Ti–29Nb–13Ta–4.6Zr alloy surface using XPS and AES
Yuta Tanaka,Masaaki Nakai,Toshikazu Akahori,M. Niinomi,Yusuke Tsutsumi,Hisashi Doi,Takao Hanawa +6 more
TL;DR: The surface oxide film on a Ti-29Nb-13Ta-4.6Zr alloy (TNTZ) was precisely characterized using X-ray photoelectron spectroscopy (XPS) and Auger electron spectrography (AES) to understand the composition and chemical state of the surface oxide films of TNTZ as discussed by the authors.
Journal ArticleDOI
Development of high Zr-containing Ti-based alloys with low Young's modulus for use in removable implants
TL;DR: In this paper, the effect of Mo addition on the microstructures, Young's moduli, and tensile properties of Ti-30Zr-(0, 8 ¼% Mo) alloys was investigated.
