دانلود کتاب Life Assessment of Hot Section Gas Turbine Components - Proceedings of a Conference Held at Heriot Watt University, Edinburgh, UK

This book contains the proceedings of a conference held at Heriot Watt University, Edinburgh, 5-7 October 1999. The contents include: Design and Life Management; Cracks and Lifing; Continuum Damage; Coatings; Low Ductility Materials; Remaining Life Assessment; Repair Technology. The importance of maintaining the safety and integrity of gas turbines was the main theme of the conference, covering the important issues for both aero and industrial engines. Over three days in October 1999, British and International engineers and scientists debated the critical issues associated with design, creep and fatigue crack growth, coating technologies, new materials, repair and maintenance of hot section components.
