Oxidation of Metals. 40:179-196
Heat-resistant alloys used in mixed-oxidant environments rely on the formation of a chromia, alumina, or silica surface film for corrosion resistance and the presence of second-phase precipitates in the matrix often for their strength properties. The

The corrosive degradation of high-temperature alloys in environments containing more than one oxidant cannot, in general, be predicted from a knowledge of the response of the materials to the individual oxidants. In the present study, the phenomenolo

Crystal structure characterization of materials at very high spatial resolution by convergent beam electron diffraction (CBD) analysis has been receiving increasing attention since the advent of the modern probe forming electron microscopes. The comb

While previous analyses of dislocation-inclusion interactions during the creep of dispersion strengthened systems have generally concluded that the dislocation climbs over the inclusion, detailed consideration of the associated elastic and diffusive

The interaction of environment with alloy microstructure can significantly alter the mechanical properties of the alloy. In this study, a 30 Cr-30 Ni austenitic steel was carburized under two different thermodynamic conditions whereby two distinct mi

The crystal structure and chemical composition of the intermetallic phase in a Fe-20%Cr-4%Al-0.5%Y (wt. %) alloy were investigated by electron microscopy. Convergent beam diffraction studies revealed that the intermetallic phase forms in three differ

The interaction of environment with the mechanical properties can generally be traced to the modification of microstructure induced by changes in alloy chemistry. Evidently, such changes will depend critically on the activity of the gaseous species a

The requirement to improve efficiency in pyrolytic furnaces has led to increased operating temperatures (>1000°C), shorter residence times and higher heat fluxes. The greater severity in operating conditions has increased the incidence of failures.
