The “reactive element effect”, modified from its earlier representation of the “rare earth effect”, is a well known term within the oxidation community. It describes several beneficial outcomes on the oxidation behavior of alumina and chromia

The microstructures and oxidation behaviour of the modified Tribaloy T-800 alloys by additions of yttrium and yttrium plus aluminium have been studied. At the presence of yttrium alone, the oxidation rate decreased, and the selective oxidation of chr

The oxidation behavior of a Co32Ni21Cr8Al0.6Y (wt%) alloy with and without the addition of 3.5 wt% rhenium, 2 wt% aluminum or a combination of the two was investigated at 1000 °C. Results showed that increasing the Al content from 8 to 10 wt% led to

The strains in alumina thin films growing on high-temperature alloys at 1,000−1,100°C and during cooling have been successfully measured in-situ using a novel x-ray technique, exploiting synchrotron radiation at the Advanced Photon Source at Argon

The interfacial chemistry that developed as a result Al2O3-scale growth on γ-Νi + γ′-Ni3Al alloys at 1150 °C was studied using scanning Auger microscopy after the oxide layer was scratched to spall under ultra-high vacuum. The extent of scale s

Thermally grown oxide scales are often under compressive residual stresses, especially upon cooling, which can lead to spontaneous spallation and a loss of their protectiveness. This study uses nickel oxide formed on different purity of nickel as an

In the context of solid oxide fuel cell (SOFC) applications, the adhesion strength and failure location of chromia scale that developed on 430 stainless steel after various surface modifications prior to oxidations between 600 and 800 °C were evalua
