Based on an EU project, 'Cyclic oxidation testing - development of a code of practice for the characterisation of high temperature materials performance' (COTEST), this volume provides the essential background to an appropriate code of practice. Drawing on its distinguished editor and a team of contributors, the book reviews the range of existing test procedures and summarizes research on the influence of various test parameters on thermal cycling oxidation behavior, including both long dwell and short dwell thermal cycling oxidation. It then describes the resulting code of practice that is being considered by the ISO/TC 156 Working Group 13 responsible for an appropriate international standard.
