Abstract:

Nimonic-75 has been reacted in low partial pressures of CO₂, H₂O, CO, CH₄, N₂, and various mixtures of these gases at temperatures in the range 750–1000°. Ten different steels have been studied in a fivecomponent gas mixture at temperatures between 500–750° and in a number of (CO + H₂+ H₂O) mixtures at 500° and 600°. No gross effects have been found on any of the materials tested under the various conditions of exposure, and the most significant phenomena in environments of practical importance are decarburisation and/or preferential oxidation of certain alloy constituents.
