Research On Rapidly Solidified Alloys

This volume details the principles underlying rapid solidification processing, material structure and properties, and their applications. This practical resource presents a manifold approach to both amorphous and crystalline rapidly solidified metallic alloys.;Written by over 30 internationally acclaimed specialists in their respective fields, Rapidly Solidified Alloys: surveys nucleation and growth studies in undercooled melts; examines various processes for the production of rapidly solidified alloys; discusses the compaction of amorphous alloys; describes surface remelting treatments for the rapid solidification of surface layers and the resultant improved workpiece properties; covers the closely related topics of structural relaxation, atomic transport and other thermally induced processes; demonstrates microstructure-property relationships in rapidly quenched crystalline alloy systems and their beneficial effects in applications; and elucidates the basic, engineeering, and applications-oriented magnetic properties of amorphous alloys.;Furnishing more than 2300 literature citations for further study of specific subjects, Rapidly Solidified Alloys is intended for materials, mechanical, product, and civil engineers; metallurgists; magneticians; physicists; physical chemists; and graduate students in these disciplines.

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.

The report describes the study of rapidly solidified alloys including methods of preparation, Processing and characterization using a variety of techniques such as TEM, analytical electron microscopy, and x-ray diffraction.
