Aluminum–Lithium Alloys: Process Metallurgy, Physical Metallurgy, and Weldingprovides 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.
