Various textures in Pt-Fe alloys; all BSE images. (A) A 140 μm composite grain of isoferroplatinum (Ifp) and tetraferroplatinum (Tfpl). The three arrows point to differences in their contacts; the two outer arrows shows a close sharp contact, whereas the middle arrow indicates a gap. (B) An 80 μm irregular composite grain of isoferroplatinum (Ifp) with areas of tulameenite (Tul). Two arrows indicate gaps between the two phases. (C) A 120 μm euhedral crystal of tetraferroplatinum with darker bands of Ni-rich tetraferroplatinum (arrows). The bottom-right arrow shows possible deformation of the bands along the edge. (D) The banded portion of a 90 μm isoferroplatinum (Ifp) grain with dark (BSE) bands (arrows) of tulameenite (Tul). The dashed lines follow the curved pattern that suggests deformation after band formation. (E) A 160 μm composite grain with irregular areas (dark BSE) of tetraferroplatinum (Tfpl) and tulameenite (Tul) in isoferroplatinum (Ifp). The contact between the Tfpl and Ifp does not have any gaps for most areas. The arrow indicates a magnetite inclusion with <1 wt.% TiO2 (EDS).
