ABSTRACT A comprehensive review of alloying effects in nickel-based single-crystal
superalloys for turbine blades and vanes operating in a very aggressive environment of …

Abstract In memory of John Stringer (1934–2014), one of the leaders in studying the reactive
element (RE) effects, this paper reviews the current status of understanding of the effect of …

Two MCrAlY coatings with the same nominal composition, but different microstructures are
deposited onto Hastelloy® X superalloy substrates by low-pressure plasma spraying (LPPS) …

This work is an original example to compare the results obtained after calcination of Al2O3
hydroxides and oxidation of alumino‐formers alloys. FTIR and XPS signatures were …

Two MCrAlY coatings with the same nominal composition but different microstructures are
prepared by magnetron sputtering (MS) and arc ion plating (AIP). Their oxidation at 1000° C …

The effect of Al content on the oxidation behavior of NiCoCrAlYHf alloys (Ni44Al16,
Ni42Al18 and Ni40Al20) at 1100℃ is investigated in this study. It is demonstrated that the …

Ceramic materials are polycrystalline solids that are made up of metal and non-metal
elements, and inorganic crystal grains with specific crystal structures are fundamental …

This work focuses on the effects of Er stabilization on thermal property and failure behavior.
The GdErZrO/YSZ TBCs exhibit a defect fluorite structure with high thermal expansion …

Oxidation and hot corrosion behaviors of NiCrAlY, NiAlY and Ni-xMo-Al-Y (x= 1, 3, 5 and 10
wt%) alloys have been investigated. The results of the hot oxidation tests indicated that …

This study investigates the effect of Y, Hf and Y/Hf addition on oxidation behavior of
NiCoCrAl alloys at 1100° C. It is demonstrated that Hf is most effective in reducing the oxide …
