Lutetium alloys with

Although the generalized phase diagram may be used with confidence for most binary combinations, it appears it may not be valid with regard to the formation of the S phase in lutetium alloys with the hght lanthanides. On the basis of an X-ray study in both the La-Lu (section 2.8.1) and Nd-Lu (section 2.36.1) systems, no 5-phase structure was observed in the X-ray patterns of alloys that were expected to have this phase. 

Alloying of YbCotln in the series Ybi-jcR InCat (R = Y, La, Ce, Lu) has been studied for various x values (Mushnikov et al., 2002). Correlating with the size of the rare earth elements, the lattice parameters increase with x for R = Y, La, and Ce, while they decrease for lutetium. The influence of alloying on the valence transition temperature is discussed. Zhang et al. (2002) investigated the ytterbium substitution by yttrium, lutetium, and zirconiunL... 

The known phase relationships, crystallographic and thermodynamic data of the known rare earth binary phase diagrams have been critically evaluated. The intra rare earth binary alloy systems will be reported in order of increasing atomic number with the exception of scandium and yttrium, which will follow lutetium in that order. The first system to be considered is lanthanum-cerium (atomic numbers 57 and 58) followed by lanthanum-praseodymium (atomic numbers 57 and 59), etc. Following... 

Anderson et al. (1958) measured the effect of lutetium additions on the superconducting transition temperature of lanthanum and reported that alloys containing 55 and 80 at% La each had the lanthanum dhcp structure. These results are consistent with those reported above by Lundin. 

In his investigation of the nature of the formation of the Sm-type structure, Lundin (1966) included some alloys in the neodymium-lutetium system that combine the heaviest of the heavy lanthanides with the heaviest of the light lanthanides that still have the dhcp structure. His neodymium metal was 99.9 -I- wt% pure...
