 Beta-type T-based alloys are increasingly used in biomaterials due to their excellent mechanical, physical, and biological performance, with low modulus beta-type T-based alloys being developed as an alternative orthopedic implant material that can provide good biological fixation through bone tissue in growth into the porous network. This paper reviews recent developments of biomedical T-based alloys, including their fundamental requirements, basic phases, alloying elements, mechanical properties, thermal treatment, grain size, texture, and limitations, as well as the influence of microstructural configurations on mechanical properties and prospects and challenges of porous T-based alloys.
