Titanium alloys are made up of titanium and other chemical elements. These alloys have high tensile strength and toughness. They are light-weight, have excellent corrosion resistance, and can sustain high temperatures. They are used in medical devices, jewelry, aircraft, and spacecraft. They are also used in highly stressed components of sports cars as well as some premium consumer electronics and sports equipment. Titanium alloys are commonly divided into four categories which include alpha alloys, near-alpha alloys, alpha and beta alloys, and beta and near beta alloys. These alloys are heat treated for a variety of purposes, the most important of which is to improve strength by solution treatment and aging for optimizing specific properties, like fatigue strength, fracture toughness, and high temperature creep strength. This book provides significant information to help develop a good understanding of titanium alloys. It explores all the important scientific and technological aspects of these alloys in the modern day. Researchers and students in this field will be assisted by this book.
