Test methods and data on the mechanical properties of protective oxide scales

摘要: The present paper describes the key mechanical properties of oxide scales with regard to model equations and investigation methods. Modified test methods are introduced for determination values describing scale failure, growth stresses in oxides creep scales. Furthermore, a summary fracture data from literature is given. As conclusion it discussed that failure strains can be estimated using basic property like toughness geometrical parameters as physical defect size, interface roughness, thickness etc. without complicated tests. In end universal diagram introduced, which behavior
