CeScSi- and CeFeSi-type structures in compounds derived from GdTiGe
Journal of Alloys and Compounds(2000)
摘要
Physico-chemical analysis techniques, including X-ray phase analysis and metallographic analysis were employed in investigations of the solid solutions based on GdTiGe compounds. These solid solutions have existence regions of the CeScSi-type phase, the CeFeSi-type phase and of their mixture. Gd0.9TiGe, SmxGd1−xTiGe (x=0–0.1, 0.9–1), GdScxTi1−xGe (x=0–0.1), YxGd1−xTiGe (x=0–1), Gd{Zr, Hf, V, Nb, Cr, Cu}0.15Ti0.85Ge, Gd{V, Mn}0.3Ti0.7Ge, GdTiGe0.9Si0.1 form coherent mixtures of the CeScSi-type and CeFeSi-type phases, while GdTi0.9Ge and the solid solutions SmxGd1−xTiGe (x=0.2–0.9), GdScxTi1−xGe (x=0.15–1), GdMo0.15Ti0.85Ge, Gd{Zr, Hf, Nb}0.3Ti0.7Ge, GdTiGe0.9{C, Sn, Pb}0.1 form the CeScSi-type phase only. GdTiGe0.9 forms in the CeFeSi-type structure.
