Thermal and structural properties of fusion related materials

This study presents a compilation of the thermal and structural properties of materials usually considered in fusion experimental devices and research work related to near term experimental machines and future prototype power plants. The thermal and structural properties of fusion power plant materials are tabulated primarily as a function of temperature. The range of temperatures for the tabulated properties is from room temperature to the melting point. For materials in the liquid state properties start at the melting point and extend to the highest anticipated operational temperature. Material properties included in this study are: poison ratio, density, specific heat capacity, thermal conductivity, yield stress, usually at 0.2% strain, ultimate stress, usually tensile, elastic modulus, and coefficient of thermal expansion. The literature search clearly demonstrated that although knowledge of the properties of several materials is quite satisfactory for both unirradiated and irradiated, conditions, for the majority of material properties, especially under irradiation conditions, knowledge is very poor.
