Request a sales quoteThis book is concerned with providing a fundamental basis for understanding the alloy-gas oxidation and corrosion reactions observed in practice and in the laboratory. Starting with a review of the enabling thermodynamic and kinetic theory, it analyzes reacting systems of increasing complexity. It considers in turn corrosion of a pure metal by a single oxidant and by multi-oxidant gases, followed by corrosion of alloys producing a single oxide then multiple reaction products. The concept of “diffusion paths” is used in describing the distribution of products in reacting systems, and diffusion data is used to predict reaction rates whenever possible.
- Provides a logical and expert treatment of the subject for use as a guide for advanced-level academics, researchers and practitioners
- Text is well supported by numerous micrographs, phase diagrams and tabulations of relevant thermodynamic and kinetic data
- Combines physical chemistry and materials science methodologies
Upper-level undergraduate and graduate students, professionals, researchers and consultants in the field of high temperature corrosion resistance

David John Young
David Young was educated at the University of Melbourne then worked in Canada for 9 years (University of Toronto, McMaster University, National Research Council of Canada) on high temperature metal-gas reactions. Returning to Australia, he worked for BHP Steel Research then joined the University of New South Wales. There he led the School of Materials Science & Engineering for 15 years, and has carried out extensive work on high temperature corrosion in mixed gas atmospheres.
His work has led to over 350 publications, including the books Diffusion in the Condensed State (with J.S. Kirkaldy), Institute of Metals (1988) and High Temperature Oxidation and Corrosion of Metals, 1st ed., Elsevier (2008). It has been recognized by his election to the Australian Academy of Technological Sciences and Engineering, the U. R. Evans Award, Institute of Corrosion Science & Technology, UK, the High Temperature Materials Outstanding Achievement Award, Electrochemical Society, USA and election as Fellow, Electrochemical Society.
