The final report has been divided in six sections. The first one is an introduction. In the second section, the theory of dilute-solutions ultralloys from tungsten sintering with special eutectic applications is presented, together with a comprehensive literature survey including 95 references. In the third one, the results for the work function evaluation of tungsten-rhenium sintered alloys, obtained by using thermionic emission microscopy, are presented. The influence of rhenium content in the range 3 percent to 30 percent, and temperature, between 1946 to 2339K in the work function are reported. The fourth section includes the determination of effective work function, normal spectral emissivity, recrystallization temperature and microhardness of tungsten-rhenium and tungsten-rhenium-thoriated alloys, in the temperature range between 1400 to 2500K. Section No. 5 summarizes the research on the influence of heating time, temperature and alloying content of rhenium in the work function of tungsten alloys as determined in the Vacuum Emission vehicle. Finally, in the last section, the mechanical properties of tungsten-30 percent rhenium were investigated by using an Instron tensile testing equipment with a high temperature, ultrahigh vacuum system. The relationship between the normalized Young's modulus, ultimate tensile strength, yield strength, elongation and test temperature was examined. (Author).

Progress in Astronautics and Rocketry, Volume 3: Energy Conversion for Space Power focuses on the use of dependable electric power sources on space vehicles. Composed of various literature, the book first discusses the physics of thermoelectricity, thermoelectric generator of materials, the use of semiconductors in thermoelectric conversion, and the use of high temperature thermoelectric materials for power generation. The text also presents experiments on the effect of irradiation on thermoelectric materials, thermoelectric elements in space power systems, and thermionics. The book then describes photovoltaic effect and conversion of solar energy; trends in silicon solar cell technology; the use of silicon solar cells in energy conversion; and how radiation affects solar cell power systems. The text notes the specifications of batteries if used in communications satellites; the use of positive-displacement engines and turbines on cryogenic power systems; and the characteristics of magnetohydrodynamic (MHD) generators in space power conversion. The book is a good source of information for readers and scientists wanting to explore the potential of energy conversion in space power technology.
