The other involved ternary titanium alloy system, Ti-Al-Fe ternary system, was investigated with CALPHAD method first to determine target compositions and desired phases, and then characterized experimentally with scanning electron microscopy (SEM) in order to establish the relationship between process parameters and microstructure. Based on the combining results from CALPHAD and selected experiments, a new Ti-Al-Fe casting titanium alloy was designed and produced with induction melting. Microstructure characterization and mechanical property testing were conducted to examine the potent of this new alloy and establish the preliminary structure-property relationship in the as-cast condition. Besides regular scanning electron microscopy (SEM), transmission electron microscopy (TEM) was also applied to investigate the effect of certain nano-size microstructural features linked to mechanical properties. Finally, a laboratory-scale manufacture framework was constructed in OSU facility, including vacuum induction skull melting (ISM), gravity tilt-pour casting, and permanent metallic mold casting. This new framework was used to manufacture a prototype casting connecting rod with the new Ti-Al-Fe casting alloy served as conceptual validation for further industrialization. A preliminary cost analysis was also presented in this work to illustrate its commercialization potent compared with the current industry applications (e.g. alloy and process).

Designed to support the need of engineering, management, and other professionals for information on titanium by providing an overview of the major topics, this book provides a concise summary of the most useful information required to understand titanium and its alloys. The author provides a review of the significant features of the metallurgy and application of titanium and its alloys. All technical aspects of the use of titanium are covered, with sufficient metals property data for most users. Because of its unique density, corrosion resistance, and relative strength advantages over competing materials such as aluminum, steels, and superalloys, titanium has found a niche in many industries. Much of this use has occurred through military research, and subsequent applications in aircraft, of gas turbine engines, although more recent use features replacement joints, golf clubs, and bicycles.Contents include: A primer on titanium and its alloys, Introduction to selection of titanium alloys, Understanding titanium's metallurgy and mill products, Forging and forming, Castings, Powder metallurgy, Heat treating, Joining technology and practice, Machining, Cleaning and finishing, Structure/processing/property relationships, Corrosion resistance, Advanced alloys and future directions, Appendices: Summary table of titanium alloys, Titanium alloy datasheets, Cross-reference to titanium alloys, Listing of selected specification and standardization organizations, Selected manufacturers, suppliers, services, Corrosion data, Machining data.

Titanium and its alloys have been widely used as biomedical implant materials due to their low density, good mechanical properties, superior corrosion resistance and biocompatibility when compared with other metallic biomaterials such as Co–Cr alloys and stainless steels. Recently, β-type titanium alloys have been increasingly considered as excellent implant materials because of the remarkable combination of high strength-to-weight ratio, good fatigue resistance, relatively low Young's modulus, good biocompatibility and high corrosion resistance relative to conventional titanium biomaterials. This book covers recent information about biomedical titanium alloy development and 3D printing. Chapters describe the processing, microstructure, mechanical properties and corrosion properties in detail. Information about the surface modification of titanium alloys for biomedical applications, and manufacturing of titanium alloys by new technologies (such as selective laser melting and electron beam melting), is also presented. Readers will learn about the various types of biomedical titanium alloys, their advantages and disadvantages, their fabrication methods and medical applications. This book is a useful handbook for biomedical engineers, metallurgists and biotechnicians seeking information about titanium-based alloys for biomaterials research and development.
