Corrosion by Liquid Metals, 1970

The Corrosion Resistant Metals Committee and the Nuclear Metallurgy Committee of the Institute of Metals Division of The Metallurgical Society of AlME sponsored a 2-1/2 day symposium on "Corrosion by Liquid Metals". The symposium was held in Philadelphia, October 13-15, 1969, during the 1969 Fall Meeting of the Metallurgical Society and the Materials Engineering Con­ gress of the American Society for Metals. Cosponsors included the American Society for Metals and the American Nuclear Society. The purpose of the symposium was to bring together the several aspects of the subject of corrosion by liquid metals, so that perspective could be provided on the entire subject, to help in­ dividuals dealing with liquid metal corrosion problems acquire a sound basis of understanding, and to provide an opportunity for discussion between those doing research in this field. An exposition of the subject is timely, in view of the in­ creasing development of liquid metal heat and power sources for special purposes, including heat-pipe systems, NASA's SNAP power systems, and the AEC's liquid metal fast breeder reactor system. This book contains the proceedings of the symposium divided into four separate topics: I. Corrosion of Steels by Sodium, II. Alkali-Refractory Metal Interactions, III. Corrosion by Non-Alkali Metals, and IV. Analysis of Solid-Liquid Metal Inter­ actions (two sessions).
