This paper presents the influence of the cycling frequency on the Cr2O3 scale adherence during thermal cycling. Oxidation was performed on pure chromium in air between 800 and 1000 °C. It has been shown that material losses due to spallation are mor

The effect of small amounts of water vapour on the isothermal high-temperature oxidation behaviour of powder-metallurgical (PM) chromium in Ar/20% O 2 and N 2 /20% O 2 has been studied. Additional oxidation experiments were performed with isotopicall

Thin layer activation (TLA) has been applied to a study of the high-temperature cyclic oxidation behaviour of pure and yttrium-implanted chromium, taking advantage of the high area selectivity of the technique. On pure chromium, two different sample

The oxidation behaviour of the γ-TiAl based intermetallic alloys Ti–42Al–8.5Nb–0.2W–(Si,B,Y), Ti–46Al–8.5Nb–1Ta–(C,Si,B,Y), and Ti–47Al–2Cr–2Mo–(Si,B) (composition in at.%) in air at 700, 800 and 900 °C was studied in compar

The contamination of consumer products, e.g. food, during production, storage and/or transport, due to release of chemicals caused by contact with technical components is of some concern. Various methods can be used to study the release of these chem

In-situ stress determinations by X-ray diffraction have been performed during pure iron oxidation (p(O 2 ) = 2 x 10 -3 Pa, T = 800°C). On yttrium implanted specimens the stress level is close to zero before oxidation. On CeO 2 coated specimens, the

Yttrium implanted and unimplanted pure iron oxidation behaviour were studied by thermogravimetry, scanning electron microscopy (SEM) and in situ X-ray diffraction at T=700°C and P O2 =0.04 Pa for 24h to determine the yttrium implantation effect on s
