Fa. Khalid et al., MICROSTRUCTURAL CHARACTERISTICS OF HIGH-TEMPERATURE OXIDATION IN NICKEL-BASE SUPERALLOY, Journal of materials engineering and performance, 6(2), 1997, pp. 219-222
High-temperature oxidation behavior of a nickel-base superalloy is exa
mined using optical and scanning electron microscopical techniques, Th
e morphology of the oxide layers developed is examined, and EDX microa
nalysis reveals diffusion of the elements across the oxide-metal inter
face, Evidence of internal oxidation is presented, and the role of str
uctural defects is considered, The morphology of the oxide-metal inter
face formed in the specimens exposed in steam and air is examined to e
lucidate the mechanism of high-temperature oxidation.
