Abstract
The inter-metallic phase (Al(13.28)Si(2.72))(Fe(1.19)Ni(2.81)) was obtained by high-pressure sinter-ing (HPS) of a mixture with an elemental atomic ratio corresponding to (Al,Si)(5)(Fe,Ni). The space group was determined to be C2/m with Z = 2. The structure model contains three co-occupied sites with occupancy ratios of Si:Al = 0.679:0.321, Ni:Fe = 0.46:0.54 and Ni:Fe = 0.94:0.06, and five sites with full occupancy of Al atoms.
