    Abstract

    The creation of superior heat-resistant materials is one part of the classical problem of efficiently converting thermal energy into ordered kinetic energy and will remain an important part so long as the Second Law of Thermodynamics is a guiding principle in the improvement of heat engines.

    This paper describes an investigation of chromium-base alloys, a class of heat-resistant materials not well known. The investigation was supervised during its entirety—a period of 3½ yr.—by the War Metallurgy Committee of the National Defense Research Committee, through contract with Climax Molybdenum Co. It was part of a project entitled “Development of Heat-Resistant Metals for Gas Turbine Parts.” In particular, the heat-resistant metals being sought were for use as gas-turbine blades rotating in an oxidizing atmosphere at temperatures up to 1600 F. (870 C.). During the final year of the investigation, the alloys were applied experimentally as erosion-resistant materials for ordnance uses under the supervision of Division One, NDRC.

    This paper, therefore, is based in whole or in part on work done for the Office of Scientific Research and Development under Contracts OEMsr-457 and OEMsr-1273.
