Book excerpt: 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.

Book excerpt: Rapidly Quenched Metals 6, Volume 1 covers the proceedings of the Sixth International Conference on Rapidly Quenched Metals held at Le Centre Sheraton, Montreal, Canada from August 3 to 7, 1987. The said conference discusses a wide variety of topics in the field of rapidly solidified metals. The book is divided into two parts. Part 1 covers topics that involve the formation and transformation in metallic materials; amorphous metals; the applications of mechanical alloying; and rapid melting and quenching. Part 2 discusses the formation and structure of amorphous alloys, which includes topics such as the metastability of amorphous phases; amorphous alloy powders; and studies about the properties of different amorphous alloys. The text is recommended for those involved in materials science and metallurgy, especially those studying rapidly solidified metals and amorphous alloys.

Book excerpt: Professor Pol Duwez of the California Institute of Technology, Pasadena, USA, developed a method in 1960 to solidify metallic melts at cooling rates exceeding about 105 K/sec. It was shown that under these non-equilibrium conditions it was possible to obtain supersaturated solid solutions, metastable crystalline inter mediate phases and even amorphous phases under appropriate quench ing conditions and for suitable alloy compositions. Subsequently, several other techniques have also been developed to achieve these non-equilibrium effects. A common feature of all these rapid quench ing techniques ~ow collectively referred to as splat quenching, liquid quenching, melt quenching or liquisoi quenching) is that quenching is carried out from the liquid state at very high cooling rates. However, the shape and size of the quenched product may be different depending on the technique employed. The method of melt spinning- in which a continuous stream of liquid jet is impinged against a conducting wheel rotating at a high speed - has become the most popular since long and continuous ribbons of uniform cross section can be obtained. Although started only about 20 years ago, the rapid quenching technique has come to be established as a standard method to produce metastable effects. The activity in this area is now world-wide as evidenced by the organization of three international conferences devoted exclusively to this topic. The first one was held in Brela, Yugoslavia (1970), the second in Massachusetts, Cambridge, USA (1975) and the third at Sussex, UK (1978).
