A shape-memory alloy (SMA) refers to a type of alloy that deforms when cold but returns to its pre-deformation shape on being heated. The parts made from SMA are lightweight and solid-state alternatives for traditional actuators, such as motor, and hydraulic and pneumatic based systems. They are also useful for creating hermetic joints in metal tubing. The two most common SMAs are nickel-titanium (NiTi) and copper-aluminium-nickel. SMAs can also be made by alloying copper, iron, zinc and gold. SMAs exhibit varying shape-memory effects and the two most prevalent effects are one-way SMA and two-way SMA. The SMAs can be created through casting in which vacuum arc melting or induction melting is used. They have applications in various areas such as orthopedic surgery, aircraft and spacecraft, robotics, smartphone cameras, valves, optometry, medicine, and dentistry. This book presents the researches that have transformed the understanding of the properties and applications of shape-memory alloys. It is appropriate for students seeking detailed information in this area of metallurgy as well as for experts.

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.

Titanium alloys are typically stronger than aluminum alloys and are lighter than steel. They have exceptional corrosion resistance and high tensile strength at extreme temperatures. They are used in numerous industries such as transportation industry, chemical industry, aerospace industry, and power generation industry. They can be easily welded and have exceptional formability. Titanium alloys have long been utilized for treating traumatic bone fractures. They are also widely utilized in the production of bone plates and metal orthopedic joint replacements. These alloys are a good substitute for stainless steel because of their easier machining capabilities, superior corrosion resistance, and lower stiffness. This book contains some path-breaking studies on titanium alloys. The readers would gain knowledge that would broaden their perspective on their microstructure, properties, and applications.
