[en] Recent research on the low- and high-temperature properties of two beryllium-niobium intermetallic compounds, Be₁₂Nb and Be₁₇Nb₂, is reviewed and discussed. Strength (bend and compression), hardness and fracture toughness has been mapped as a function of test temperature up to 1,200 C. Results for hot-isostatically-pressured Be₁₂Nb and Be₁₇Nb₂ are highlighted illustrating the potential for reasonable strength at both low and high temperatures. Chemical compatibility between Be₁₂Nb and several high-temperature materials such as SiC, Al₂O₃, MoSi₂ and various refractory metals is evaluated. Limitations for the structural use of the beryllides are identified and discussed including low-temperature toughness, intermediate-temperature embrittlement, high-temperature creep strength and composite compatibility

[en] Multilayer Nb₃Sn shields have been designed, fabricated, and tested for use in low field, e.g. superconducting electronics, applications. Magnetic field profiles, shielding factors, and thermal effects are reported for these shields. The quality of the shields depends strongly on the reaction temperature used to form the Nb₃Sn layers with lower reaction temperatures forming better quality shields. Nearly ideal behavior was observed with a reaction temperature of 750⁰C
