The ternary Laves phase Nb(Ni1−xAlx)2 with MgZn2 -type

Alloys with nominal composition Nb(Ni1−xAlx)2 (xAl=0.15, 0.23, 0.30, 0.38, 0.46, 0.54, 0.62, 0.69, 0.77, 0.85) were investigated by means of X-ray powder and single crystal diffraction, optical microscopy, electron probe microanalysis (EPMA) concentrating on structural details of the C14 MgZn2-type Laves phase. Rietveld refinements of X-ray powder data (0.23
