“…Owing to the diversity of mechanisms for stress generation in oxide scales, the modeling of its time evolution has been possible only for cases where an individual oxide phase grows on the metallic substrate [10,11] and the growth stresses are mainly attributed to strain sources located at oxide grain boundaries perpendicular to the interfaces. The applicability of those approaches is only limited to oxidation cases where multi-phase oxide scales grow, with metal as well as oxygen having different mobilities within each different oxide phase.…”

The evolution of microstructure and growth stresses in oxide scales grown on a (110) iron single crystal surface at 650°C was studied by electron backscatter diffraction and in situ energy-dispersive diffraction with synchrotron radiation. Within this high temperature regime, the oxidation kinetics and scale microstructure were not significantly different from those encountered in the oxidation of ferrous polycrystals. Thus, epitaxial strains did not determine the stress state within the oxide scale. Relevant sources of growth stresses were inferred to be volumetric differences between the iron oxides in the early stages, and later, inner oxide formation, scale consumption as well as pore formation. These sources caused time-dependent stress cycles in magnetite and wüstite during oxidation. In the hematite layer stress cycles did not occur and creep appeared to be the predominant stress relieving mechanism. On cooling, the differences in thermal expansion caused residual stress gradients through the oxide scale.

“…Since this new oxide is laterally constrained by the surrounding oxide grains as well as by the underlying substrate, high compressive stresses develop. After a maximum compressive stress level is reached in the scale, creep-induced stress relief begins to balance the intrinsic oxide growth stresses ͑Veal and Paulikas, 2008;Panicaud et al, 2006;Limarga et al, 2004͒, and the stress level in the oxide scale approaches a steady state condition which, in the present case, is close to Ϫ300 MPa.…”

“…and not fully understood for a number of metal-oxide systems ͑Veal et Clarke, 2003;Panicaud et al, 2006͒. Another important issue that affects the oxidation resistance of iron aluminides is the appearance of less protective Al 2 O 3 polymorphs, generally monoclinic -Al 2 O 3 or cubic ␥-Al 2 O 3 , which only later transform into the stable ␣-Al 2 O 3 . These phases are formed when iron aluminides are subjected to low oxidation temperatures ͑below 1000°C͒ and have a detrimental impact on the oxidation resistance of the alloy ͑Grabke, 1999; Levin and Brandon, 1998͒.…”

Internal stresses and textures of nanostructured alumina scales growing on polycrystalline Fe₃Al alloy

The evolution of internal stresses in oxide scales growing on polycrystalline Fe 3 Al alloy in atmospheric air at 700°C was determined using in situ energy-dispersive synchrotron X-ray diffraction. Ex situ texture analyses were performed after 5 h of oxidation at 700°C. Under these conditions, the oxide-scale thickness, as determined by X-ray photoelectron spectroscopy, lies between 80 and 100 nm. The main phase present in the oxide scales is ␣-Al 2 O 3 , with minor quantities of metastable -Al 2 O 3 detected in the first minutes of oxidation, as well as ␣-Fe 2 O 3 . ␣-Al 2 O 3 grows with a weak ͑0001͒ fiber texture in the normal direction. During the initial stages of oxidation the scale develops, increasing levels of compressive stresses which later evolve to a steady state condition situated around Ϫ300 MPa.

“…12,14) Oxide-growth stress has also been reported. [10][11][12][13]15) It occurs because of a difference in volume change between the oxide scale and substrate steel (Pilling-Bedworth ratio) and a lattice misfit at the scale/steel interface. Taniguchi et al 10) measured the oxide-growth stress of iron using flexure method and observed that the specimens showed considerable bending.…”

“…[10][11][12][13][14][15] In the case of cooling of steel with an oxide scale from a high temperature, the difference of thermal expansion coefficients between the scale and substrate steel causes a stress in the scale, resulting in scale fracture or detachment. 12,14) Oxide-growth stress has also been reported.…”

Development of a strain in oxide scale during phase transformation of FeO was investigated by a flexure method. A pure iron foil was oxidized on only one side, and the formed FeO was transformed at 400 or 500°C. In-situ observation of the bending behavior of the foil-formed specimen during the phase transformation of FeO was performed. Compressive strain develops in the scale in the early stage of the phase transformation, following which a significantly large expansion strain develops. Such a strain development corresponds to the two-step phase transformation of FeO and can be explained by the volume change of the scale considering the non-stoichiometry of FeO.
