New Developments of Ti-Based Alloys for Biomedical Applications
TLDR
Efforts have been made to reveal the latest scenario of bulk and porous Ti-based materials for biomedical applications, emphasizing their current status, future opportunities and obstacles for expanded applications.Abstract:
Ti-based alloys are finding ever-increasing applications in biomaterials due to their excellent mechanical, physical and biological performance. Nowdays, low modulus β-type Ti-based alloys are still being developed. Meanwhile, porous Ti-based alloys are being developed as an alternative orthopedic implant material, as they can provide good biological fixation through bone tissue ingrowth into the porous network. This paper focuses on recent developments of biomedical Ti-based alloys. It can be divided into four main sections. The first section focuses on the fundamental requirements titanium biomaterial should fulfill and its market and application prospects. This section is followed by discussing basic phases, alloying elements and mechanical properties of low modulus β-type Ti-based alloys. Thermal treatment, grain size, texture and properties in Ti-based alloys and their limitations are dicussed in the third section. Finally, the fourth section reviews the influence of microstructural configurations on mechanical properties of porous Ti-based alloys and all known methods for fabricating porous Ti-based alloys. This section also reviews prospects and challenges of porous Ti-based alloys, emphasizing their current status, future opportunities and obstacles for expanded applications. Overall, efforts have been made to reveal the latest scenario of bulk and porous Ti-based materials for biomedical applications.read more

Development of Ti-22Nb-xZr Using Metal Injection Moulding for Biomedical Applications
Anok Babu Nagaram,Thomas Ebel +1 more
TL;DR: In this article, different amounts of zirconium were added varying between 2 to 10 wt. XRD measurements revealed an increase in lattice constant effecting an increase of the carbon solubility of the Ti-matrix and, thus, a reduction of the carbide precipitation.

The molybdenum-titanium phase diagram evaluated from ab-initio calculations
TL;DR: In this paper, the authors used ab-initio calculations to investigate the Mo-Ti phase diagram and found that the \beta-phase is stable over a wide concentration range, in qualitative agreement with one of the reported phase diagrams.

Effect of calcium pyrophosphate on microstructural evolution and in vitro biocompatibility of Ti-35Nb-7Zr composite by spark plasma sintering.
TL;DR: The results demonstrated that the favorable cell viability and growth inside the pores of the composites arise from the rough micro-porous surface and the release of bioactive metal-ceramic phase ions into the biological environment.
