High temperature oxidation behaviour of single crystal superalloys RR and CMSX Creep-fatigue testing is typically performed at elevated temperatures and involves the sequential or simultaneous application of the loading conditions necessary to generate cyclic deformation/damage enhanced by creep deformation/damage or vice versa. Unless such tests are performed in vacuum or an inert environment, oxidation can also be responsible for . Figures 5(a) and 5(b) show the SEM images of fused metal part before and after being subjected to oxidation test at °C for 40 hours. The changes of appearance due to oxidation were supported by the SEM micrograph shown in Figure 5(b) indicating the formation of oxide scale on the sample’s surface. It was found that, at °C, the oxidized fused metal surface was found Cited by: 3.

Meier, Frederick S. Pettit. The present work investigates the high temperature oxidation and corrosion behaviour of high entropy superalloys (HESA). A high content of various solutes in HESA leads to formation of complex oxides, however the Cr and Al activities of HESA are sufficient to promote protective chromia or alumina formation on the surface.

An upsurge in the demand of higher power generation has been observed in the last few decades. Consequently, the mechanical components of power generation are forced to operate in the extreme working conditions for longer duration, which results in the accelerated wear and corrosion of the material.

In this book the intention is to introduce the subject of high-temperature oxi-dation of metals to students and to professional engineers whose work demandsfamiliarity with the subject.

The emphasis of the book is placed firmly on supplyingan understanding of the basic, or fundamental, processes involved in oxidation.The oxidation behavior of commercial heat resistant alloys is a sufficiently complex process that antiapating long term behavior on the basis of short term data is an uncertain matter.
