 Betatype T-Base Alloys are increasingly used in biomaterials due to their excellent mechanical, physical and biological properties. Low-modulus Betatype T-Base Alloys are being developed as an alternative orthopedic implant material with good biological fixation through bone tissue ingroth into the porous network. This paper reviews recent developments of biomedical T-Base Alloys, including fundamental requirements, basic phases, alloying elements, mechanical properties, thermal treatment, grain size, texture, and limitations, as well as microstructural configurations and fabrication methods for porous T-Base Alloys. The paper emphasizes prospects and challenges of porous T-Base Alloys, highlighting their current status, future opportunities, and obstacles for expanded applications.
