Cyclic Oxidation of Titanium Grade 2 [PDF]

open access: yesMaterials, 2020
This paper presents the results of research into the cyclic oxidation of titanium Grade 2. The value of titanium Grade 2 oxidation activation energy was determined based on an analysis of the Arrhenius diagram. The result was 205.3 kJ/mol. After cyclic oxidation at a temperature of 600 °C, the presence of oxides in an acicular system was observed on ...

Origins of a Low-Sulfur Superalloy Al2O3 Scale Adhesion Map

open access: yesCrystals, 2021
Low-sulfur single-crystal Ni-base superalloys have demonstrated excellent cyclic oxidation resistance due to improved Al2O3 scale adhesion. This derives from preventing deleterious interfacial sulfur segregation that occurs at common ppm levels of S ...
