Aluminum-Lithium Alloys: Process Metallurgy, Physical Metallurgy, and Welding provides theoretical foundations of the technological processes for melting, casting, forming, heat treatment, and welding of Al-Li alloys. It contains a critical survey of the research in the field and presents data on commercial Al-Li alloys, their phase composition, microstructure, and heat treatment of the ingots, sheets, forgings, and welds of Al-Li alloys. It details oxidation kinetics, protective alloying, hydrogen in Al-Li alloys, and crack susceptibility. It also discusses grain structure and solidification, as well as structural and mechanical properties. The book is illustrated with examples of Al-Li alloy applications in aircraft structures. Based on the vast experience of the coauthors, the book presents recommendations on solving practical problems involved with melting and casting ingots, welding of Al-Li alloys, and producing massive stampings for welded products. Provides comprehensive coverage of Al-Li alloys, not available in any single source. Presents research that is at the basis of the production technology for of ingots and products made of Al-Li alloys. Combines basic science with applied research, including upscaling and industrial implementation. Covers welding of Al-Li alloys in detail. Discusses gas and alkali-earth impurities in Al-Li alloys. Describes technological recommendations on casting and deformation of Al-Li alloys.
