The world of materials is complex, exciting and challenging. This volume of Pressure Vessels and Piping: Materials and Properties is an attempt to share the excitement, knowledge and awareness. The chronological development of high temperature materials has been highlighted in several reviews. The development of new materials to achieve better efficiency and cost effectiveness of power generating and allied industries has been discussed through several original contributions. High temperature mechanical properties including creep, fatigue and fracture, the key criteria for safe life design of components along with physical metallurgy and corrosion aspects for a variety of materials form the contents. The book is a valuable source of knowledge and inspiration to students, researchers, scientists, engineers, plant personnel and technology managers.
