Machining of Spherical Component Fabricated by Selected Laser Melting, Part II: Application of Ti in Biomedical
Ti and Ti-Based alloys have unique properties such as high strength, low density and excellent corrosion resistance. These properties are essential for the manufacture of lightweight and high strength components for biomedical applications. In this paper, Ti properties such as metallurgy, mechanical properties, surface modification, corrosion resistance, biocompatibility and osseointegration in biomedical applications have been discussed. This paper also analyses the advantages and disadvantages of various Ti manufacturing processes for biomedical applications such as casting, powder metallurgy, cold and hot working, machining, laser engineering net shaping, superplastic forming, forging and ring rolling. The contributions of this research are twofold, firstly scrutinizing the behaviour of Ti and Ti-Based alloys in-vivo and in-vitro experiments in biomedical applications to determine the factors leading to failure, and secondly strategies to achieve desired properties essential to improving the quality of patient outcomes after receiving surgical implants. Future research will be directed toward manufacturing of Ti for medical applications by improving the production process, for example using optimal design approaches in additive manufacturing and investigating alloys containing other materials in order to obtain better medical and mechanical characteristics.
Microstructural development in relation to hot working of titanium alloys
AbstractThe relationships between titanium alloy microstructures and mechanical properties are reviewed. The influence of hot working on microstructure development is discussed, and developments in high temperature processing, including superplastic forming and isothermalforging, and the use of hydrogen as a temporary alloying addition are considered. Recent work aimed at modelling the high temperature deformation and microstructure development is also examined.MST/1265
