 · Besides this region, experimental investigations were reported in [ 18, 19] for the rapidly solidified Ta 10 Fe 20 Al 70 alloy that formed the metastable icosahedral i -phase with the quasilattice constant of a = 460.0 ± 0.3 pm. Heating at 10 K min −1 gave rise to decomposition of the i -phase into Fe 4 Al 13 and TaAl 3 (ε) at about 900 K [ 18 ].

 · The experimental liquids reach a maximum of ∼18 wt% FeO *, at ∼48 wt% SiO 2 for ilmenite-saturated melts at low f O2, more differentiated melts having lower iron and higher silica. Cotectic proportions, derived from mass balance calculations, are in good agreement with data from natural samples and other experimental studies.
