“…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]. However, since SmNiAl crystalises within P62m in ZrNiAl structure type, this is not closely related to here investigated systems.…”
