Rapid solidification processing results in increased strength, and fracture and fatigue resistance of alloys, with concurrent improvements in mechanical, physical and chemical properties. This volume provides a systematic examination of this technology, including metallurgical aspects, processing methods, alloy design, and applications. Each chapter was prepared by a specialist for this volume. The text is well illustrated with more than 400 micrographs and schematics. More than 75 tables provide important reference data.

Research performed during this program demonstrated that the metastable microstructures upon which rapidly-solidified, powder metallurgy (RS/PM) aluminum alloys depend for their unique mechanical properties can be both 'recreated' using rapid solidification fusion welding processes and/or 'retained' using solid-state welding processes. Alloys investigated included Al-Fe-X dispersoid-type compositions developed for superior elevated-temperature properties and Al-Li-X alloys developed for high strength and modulus and low density. Processes found to be most effective for the joining of these alloys included rapid-solidification electron beam and capacitor-discharge welding and solid-state inertia-friction and diffusion welding. Metallurgical phenomena investigated included solidification, solid-state phase transformations, defect formation and structure-property-fracture relationships. RS/PM aluminum alloys which contain low hydrogen levels, such as the inertly produced Al-8Fe-2Mo alloy, were effectively joined using the high-energy density electron-beam welding.
