N. K. Othman, Auteur ; J. Zhang, Auteur ; D. J. Young, Auteur |Model Fe–Cr alloys containing 9, 17 or 25 wt% Cr were subjected to repeated 1 h cycles of exposure at 700 °C to flowing gas mixtures of Ar-20O2, Ar-20O2-5H2O and Ar-5O2-20H2O (all in volume %) for up to 400 cycles. The kinetics and morphological[...]

H. Yin, Auteur ; W. Y. D. Yuen, Auteur ; D. J. Young, Auteur |A low carbon, low silicon steel was oxidised at temperatures of 900–1000 °C in flowing N2–H2–H2O gas mixtures in which oxygen and water vapour partial pressures were varied independently. Scales of dense, single-phase, coarse grained wüstite gre[...]

Q. Wu, Auteur ; J. Zhang, Auteur ; D. J. Young, Auteur |The metal dusting behaviour of total 11 nickel- and cobalt-base alloys at 680 °C in a gas of 68%CO[BOND]31%H2[BOND]1%H2O (aC = 19.0, equation image = 5.4 × 10−25 atm) was investigated. All samples were electropolished and reacted in a thermal c[...]

D. J. Young, Auteur ; D. Naumenko, Auteur ; L. Niewolak, Auteur |A model Fe-20Cr-5Al-0.05Y alloy was oxidized in Ar-20%O2 and Ar-4%H2-7%H2O at 1200–1300 °C. Two-stage oxidation experiments using oxygen isotope tracers showed that inward oxygen diffusion was predominant in both gases, but more isotope exchange[...]

D. J. Young, Auteur ; J. Zhang, Auteur ; C. Geers, Auteur |Recent experimental investigations have widened the understanding of metal dusting significantly. Microscopic observations have been used to dissect dusting mechanisms. Iron dusts by growing a cementite surface scale, which catalyses graphite nu[...]
