European Networks Focus on Advanced Materials The European Networks on Advanced Materials were established in 1987 to enhance scientific and technical cooperation between research teams from different countries. With the assistance of industrial and public institutions and with the support of the Council of Europe and the Commission of the European Communities, the European Materials Research Society is continuing to develop these networks. Eleven networks have established programs, and three are in the initial stages of development (see Table). This article is part of a continuing series that focuses on the philosophies, aims and activities of the separate networks as described by their chairmen. Featured this month are Network 4 on New Methods in Metastable Alloy Production and Network 5 on High Resolution and High Sensitive Analysis of Semiconductors. A brochure detailing all the networks is available from: P. Siffert, Chairman, European Materials Research Society, Centre de Recherches Nucleaires, 23, rue de Loess, F67037, Strasbourg, France; telephone 88 28 65 43; fax 88 28 09 90.
Network 4—New Methods in Metastable Alloy Production Chairmen: J. Bottiger, Institute of Physics, Aarhus University, Denmark; B. Stritzker, Kernforschungsanlage, Ju'lich, W. Germany; M. Von Allmen, CM-S.A. Biel, Switzerland. Metastable alloys (i.e., extended solid solutions, amorphous alloys, microcrystalline phases) are at present, due to their unique properties, finding their way into various industrial products. Metallic glasses, for example, have a combination of magnetic and mechanical properties which makes them very suitable in various electrical products. Large-scale production of metastable alloys is traditionally carried out by meltspinning (i.e., fast quenching from the melt) but new methods of production have appeared in recent years. As examples, amorphous alloys can be formed by solidstate reactions (i.e. isothermal annealing) at sufficiently low temperatures that crystalline compounds will not be formed, by ion or laser irradiations, and by ball-milling (mechanical alloying). The physical mechanisms involved in the various new production methods are at present being studied very intensively in many Euro-

pean laboratories. The physical and chemical properties of this new class of alloys are also being investigated. Nineteen laboratories from nine countries are participating in this network: CMS.A., Biel; Natuurkundig Laboratorium der Universita t van Amsterdam; Istituto di Chimica Generale ed Inorganica, Torino; Institute of Physics, University of Aarhus; Metallurgy Division, School of Materials, University of Sheffield; Physics Institute, Univ. d.Bw. Munchen,, Neubiberg; University of Cambridge, Department of Metallurgy and Materials Science; Institute of Applied Physics, Univ. Berne; Department of Electronics & Electrical Engineering, Salford University; Laboratoire Mixte CNRS-Saint Gobain; Physics Department, University of Padova, Italy; Institute of Structural Metallurgy, University of Neuc
