Ternary intermetallic A–B–C systems sometimes have unexpected behaviors. The present paper examines situations in which there is a tendency to simultaneously form the compounds ABx, ACx and BCx with the same crystal structure. This causes irregular shapes of the phase homogeneity domains and, from a structural point of view, a complete reversal of site occupancies for the B atom when crossing t...
2014 Nuclear orientation experiments on In3Ce, Pb3Ce, Sn3Ce show that the first compound is well ordered, that Sn3Ce is a Kondo lattice and that further experiments must be performed in order to confirm the Kondo state of Pb3Ce. A simple interpretation is proposed to explain the behaviour of these abnormal compounds. LE JOURNAL DE PHYSIQUE LETTRES TOME 39, 1 er MARS 1978,
• Chemistries of Zr- and Ti-based compounds are reviewed in terms alloying elements gettering properties. Activation process, surface coating resistance to impurities discussed. New processes other possible applications foreseen. Metal hydrides were discovered the fifties since then have been widely studied developed, mainly for energy (batteries, hydrogen storage, compression.). In addition th...
