THEORETICAL EVALUATION OF THE PHYSICAL-PROPERTIES OF COPPER-LEAD RHEOCAST ALLOYS

The use of the copper-lead rheocast alloy as a joining material is ver y attractive in the design of the plasma-facing components of a thermo nuclear fusion reactor. Presently, experimental data on its main physi cal properties are not yet available and therefore they have been esti mated theoretically. The evaluation of the following properties is per formed at different alloy compositions: thermal conductivity, density, specific heat, elastic modulus, Poisson's ratio, coefficient of therm al expansion. Their use is suggested for preliminary calculations unti l the experimental data are obtained.
