This report presents the results of an investi gation of materials for use in an MHD generator operating at wall temperatures in the range of 3000 to 4500 F. The investigation consists of a systematic evaluation of promising materials selected after an extensive literure survey. The program, which includes high-temperature laboratory measurements of material properties and the characteristic material performance under environmental operating conditions, was designed to select the best materials for this high tem perature MHD application. The results presented include the experimental determination of elec trical resistivity, thermal expansion, and strength of several refractory conductors and insulators. The results of chemical compatibil ity tests and the environmental testing program are also included. In addition, data is pre sented from an investigation of tensile strength and tensile modulus of selected material. Author
