AMORPHOUS METALS An MRS-Europe Symposium Report The symposium entitled "Amorphous Metals and Nonequilibrium Processing" was devoted to the connections between various approaches to amorphization of metals, ranging from traditional techniques, such as melt spinning and vapor quenching, to laser irradiation, and from ionbeam mixing to solid-state reaction. Three of the six oral sessions focused on the processes, while the other three concentrated on the properties of amorphous phases as produced by the various processes. In all, the program comprised 49 scientific papers. A.R. Yavari opened the first session with a survey of the basic kinetic considerations to predict glass formation or crystallization in melt quenching. A number of speakers then discussed technical aspects of melt spinning as well as scanned CW-Laser irradiation, two techniques that yield cooling rates up to about \06K/sec. The second day was opened by an excellent plenary talk by H.K.J. Buschow discussing magnetic and electronic properties and showing perspectives on applications of amorphous metals in data recording and storage. The tone for the session on ion beams and chemical processes was set by M.A. Nicolet with a talk on what is and what isn't presently understood about amorphization by ion beams. Exciting new experiments on the amorphization by solidstate reactions were reported by two speakers later in the session. The process is carried out at a temperature too low for crystallization but sufficient for fast diffusion by one of
the component species, and promises the production of amorphous alloys of almost arbitrary dimensions. The last session on processes was devoted to ultra-rapid quenching and nanosecond or picosecond laser quench
