Titanium and its alloys are one of the important engineering materials that are becoming increasingly popular for aerospace and biomedical applications due to their wide range of desirable properties. However, these unique properties of titanium and its alloys are strongly affected by different parameters including: chemical composition, microstructure, manufacturing details and heat treatment history. On the other hand, there has been considerable interest in recent years in the development of advanced titanium alloys in nanostructured, ultrafine-grained, and/or amorphous structure to achieve high performance compared with their conventional coarse-grained counterparts. These new titanium alloys show incomparable plasticity with respect to the conventional titanium alloys. This book highlights the recent advances in the understanding of the formation, characteristics and application of titanium alloys and contains the following topics: Chapter one reviews the significance of titanium and various titanium-based alloys used in different applications, their corrosion characteristics and degradation mechanisms. Chapter two explores the scientific issues on thermo-mechanical processing of titanium alloys, with the purpose of thorough understanding of a materials microstructure, including how this may be affected or manipulated during manufacturing and processing in order to assess the material’s suitability for a given application. Chapter three and Chapter four show the application of a rapid manufacturing technology – Selective Laser Melting (SLM) to manufacture CP-Ti and biomedical beta-type titanium alloys. Chapters fiveseven present the formation and properties of biomedical titanium alloys prepared by powder metallurgy routes. Chapter eight reports the fabrication and corrosion behavior of Ni-free Ti Zr Cu Pd Sn BMGs prepared by different techniques. Chapter nine reviews the current progress in the formation, characteristics of titanium based bulk metallic glass matrix composites. Chapters ten-eleven review a strategy of formation of multiple length-scale microstructure composites in order to simultaneously enhance the strength and plasticity in nanostructured titanium alloys. In summary, this book advances the further understanding of the formation, characteristics and industrial applications for many types of titanium alloys.
