Abstract : Interest in sodium-potassium alloys as thermo-vehicles has resulted in this investigation of the corrosion effects of these alloys on various materials at elevated temperatures. While this investigation is still in progress, it is felt that the results obtained to date might be of some use to those who are confronted with problems of handling Na-K alloys at elevated temperatures. Tests were made at temperatures as high as 8000 deg C. The maximum temperature of Na-K alloy contemplated for the Argonne Laboratory's fast neutron pile is 450 - 500 deg C but, if materials can be found which will withstand Na and K at their boiling temperatures (892 deg C and 774 deg C), the field of usage of Na-K alloys will be considerably broadened.
