Pure nickel, Ni-20Cr and Ni-30Cr alloys wereexposed to conditions of erosion and corrosionsimultaneously at 700°C and 800°C. The exposureswere made using normal impact of an air stream loadedwith 20-μm alumina. The alumina particles flowed at ther

The paper examines some of the conditions that influence deviations from the ideal behavior of high temperature attack of metals, according to Wagner's model. It considers the effects of factors such as specimen shape, non-isothermal situations, allo

Autoignition of direct reduced iron (DRI) that leads to severe warming or even to uncontrollable metal fires has always been linked with the presence of moisture, being particularly severe in the presence of sea water. This is of considerable concern

Superalloys 1996 (Eighth International Symposium).
The precipitation behavior of a new nickel base superalloy, AEREXTM* 350, is examined. An understanding of the microstructure as influenced by different heat treatments is necessary in order to realize the full potential of the alloy. This paper pres

In discussing the degradation of coatings, it is necessary to consider the environments to be examined and the particular sources of data to be utilized. The questions of generation and use of test data are important because the degradation of coatin

Superalloys 1996 (Eighth International Symposium).
State-of-the-art superalloys are useful for high temperature applications, in large part, because they form protective alumina surface films by the selective oxidation of aluminum from the alloy. The adherence of the alumina to the alloy is crucial t

Publisher Summary The upper temperatures of heat cycles used in energy generation are limited by mechanical properties and resistance to attack by the ambient atmosphere. Although oxidation forms a passivating surface layer, solid particles in the ho

The transport of sulfur through growing scales may occur by chemical (solution and diffusion) or physical (gas molecule permeation) mechanisms. Both possibilities are examined theoretically for the case of NiO growing on nickel. Experiments are desig

Specimens of NiO for conductivity measurements were made from Ni foil, containing less than 25ppm total impurities, by spot welding platinum leads to the foil which was then oxidized to compact NiO at 1300°C. Four point d.c. conductivity measurement
