Phase relations of the Sm–Ni–Al ternary system at 500°C in the 40–100at.% Al region

Crystal growth of Cu2ZnSnS4 solar cell absorber by chemical vapor transport with I2

“…EDS was conducted using a 1nA probe at 25 keV, all acquisitions were performed a compositional standard used for further optimisation. Samples larger than 2 mm were embedded in Taab Hard LV resin and polished up to a 0.1 μm alumina finish (Streuers) with a Metaserv rotary polishing machine for more accurate estimation of the bulk composition via SEM-Xray EDS, as described elsewhere [37]. The same samples were also loaded on a Reichert-Jung ultramicrotome for production of thin sections (< 90 nm).…”

Structural and hydrogen sorption properties of SmNi5−xAlx system – An experimental and theoretical study

“…This behaviour reflects transitions between a, b and g phase [9]. ANi 5Àx Al x systems were extensively studied by Sorgi c et al [17e20, 10,21e24], while the SmNi-Al system was investigated with respect of phase equilibria [25,26]. Wang et al have investigated SmNiAl-hydrogen system [27,28].…”

Crystallization Process and Microstructural Evolution of Melt Spun Al-RE-Ni-(Cu) Ribbons

“…The existence of the Al 19 Sm 3 Ni 5 phase has not been established in previous studies, but according to the peaks' positions, and through a comparison with the Y alloys, this can be proposed as the stable phase appearing in the Sm alloys. Based on the similarity of the Al 23 Sm 4 Ni 6 and Al 23 Y 4 Ni 6 lattice parameters (1.5939 nm, 0.40967 nm, 1.8320 nm, and 113.09 • for the former [85], and 1.5836 nm, 0.4068 nm, 1.8311 nm, and 112.97 • for the latter [77]), this could be an acceptable assumption. Conversely, the metastable phase prevails in the Sm alloys for tougher treatments (with a similar evolution in the Cu-free alloy to that of the Cu-containing Y alloy), with the presence of the metastable phase being detected, even when heat treating beyond the third DSC reaction.…”
