Abstract

An isothermal section (at 600° C) and some melting points in the aluminium-rich corner of the Al/U/Sm system was investigated by differential thermal analysis, micrographic examination, X-ray and electron microprobe analysis and thermal diffusion studies. No ternary intermetallic compound was found in the investigated composition range. The phase boundaries of the existing single-, two- and three-phase alloys were determined. The variations with composition of the lattice parameters in the pseudobinary system SmAl₂-UAl₂ were determined. An orthorhombic (U, Sm) Al₄ intermetallic compound was found to be in equilibrium with the aluminium-rich solid solution. From this study, it was possible to conclude that samarium can be homogeneously introduced in (U/Al) fuel alloys owing to the formation of the (U, Sm)Al₄, (U, Sm)Al₃ and (U, Sm)Al₂ solid solutions.
