Progress in the materials studies of interest in the design and study of a magnetohydrodynamic vortex generator for use in a closed-cycle power conversion system is described. Experimental results of tests to determine the tensile strength properties of tantalum to its melting point are presented. Measurements of temperature creep and stress deformation definitely indicate that creep rate will rule out use of tantalum as the sole structural material at design stresses greater than 600 psi. Fabrication difficulties in the use of tungsten possibly may be overcome or alleviated by wire-wrapped construction. Design of an electron bombardment heated test facility to determine the electrical resistivity of high-temperature (2500 deg K) insulating materials is described. (auth)
