Improvement of the Oxidation Resistance of Dispersion Strengthened Nickel-Chromium Alloys.
Abstract
Experiments were conducted to improve the static and dynamic oxidation resistance of Ni/20 Cr/2 ThO2 alloys in the temperature range 1040C to 1205C. Elemental additions to the Ni/Cr/ThO2 matrix during powder preparation were made to affect the type of surface oxide which formed on the wrought product during exposure to high temperatures. The modified alloys were evaluated for static and dynamic oxidation resistance in a screening program which consisted of studies of weight change and metallography following exposure to a continuous oxidizing environment for 100 hour. Further work on the Ni/Cr/Al/ThO2 and Ni/Cr/Mn/ThO2 systems was recommended. (Author)
