Book Description
Treatise on Materials Science and Technology, Volume 20: Ultrarapid Quenching of Liquid Alloys investigates the relationship between the science and utility of materials, with emphasis on the ultrarapid quenching of liquid alloys. Topics covered range from rapid solidification of non-metals and crystalline iron-base alloys to corrosion behavior of amorphous alloys. Experimental methods in rapid quenching from the melt are also discussed. This volume is comprised of nine chapters and begins with a historical overview of various methods that have evolved for producing rapidly solidified materials. The criteria for the formation of highly metastable states and how these relate to experiment are described. Subsequent chapters explore rapid solidification of non-metals; the industrial implications of rapid solidification of iron-based alloys by means of plasma spraying; annealing effects in metallic glasses; and the corrosion behavior of amorphous alloys. The mechanical properties of metallic glasses are also considered, along with the electrical properties of rapidly solidified materials. This book should be of interest to materials scientists and engineers as well as metallurgists, researchers, and students.

Book Description
Rapidly Quenched Metals, Volume I covers the proceedings of the Fifth International Conference on Rapidly Quenched Metals, held in Wurzburg, Germany on September 3-7, 1984. The book focuses on amorphous and crystalline metals formed by rapid quenching from the melt. The selection first covers the scope and trends of developments in rapid solidification technology, rapid solidification, and undercooling of liquid metals by rapid quenching. Discussions focus on experimental method, powders, strip, particulate production, consolidation, and alloys and alloy systems. The text then examines the solidification of undercooled liquid alloys entrapped in solid; crystallization kinetics in undercooled droplets; and grain refinement in bulk undercooled alloys. The manuscript tackles the undercooling of niobium-germanium alloys in a 100 meter drop tube; influence of process parameters on the cooling rate of the meltspinning process; and the mechanism of ribbon formation in melt-spun copper and copper-zirconium. The formation and structure of thick sections of rapidly-solidified material by incremental deposition and production of ultrafine dispersions of rare earth oxides in Ti alloys using rapid solidification are also mentioned. The selection is a valuable reference for physicists, chemists, physical metallurgists, and engineers.
