Die elektrische Leitfähigkeit und die thermische Ausdehnung der Magnesium–Cadmiumlegierungen

The lattice spacings of the primary solid solutions of silver, cadmium and indium in magnesium

“…This behaviour is probably con nected with the existence of the superlattice Mg3Cd. The work of Grube and Schiedt (1930) on the equilibrium diagram of the system shows th at the area occupied by this superlattice extends, on the magnesium-rich side of Mg3Cd, to 16 atomic % cadmium at 100° C. Although no superlattice lines could be detected on the photographs in the present work, other work has shown th at the superlattice rearrangement occurs at room temperature. I t is probable that the ordering process is beginning to occur in the region 10-16 atomic % cadmium, with a consequent diminution in the strain attendant on solid solution of cadmium in magnesium.…”

Diagramme de transformation dans l'état solide des alliages cadmium-magnésium. Etude quantitative de l'ordre à grande et à courte distance

“…En vue de leur examen par diffraction des ray-ons X, les alliages sont mis sous la forme de plaquettes de poudre tr~s fine agglom6r6e par compression. -Les divergences entre les r6sultats des travaux ant6rieurs (Grube & Schiedt, 1930;Hume-Rothery & Raynor, 1940;Hirabayashi, Maniwa & Nagasaki, 1949Moore & Raynor, 1957;Kuzmenko & Kalna, 1962;Edwards, 1966;Kamath, Craig & Wallen, 1963;Kamath, 1960) toutes deux hexagonales compactes ont des param&res cristallins pratiquement identiques.
