Abstract Phase equilibria in the Al-rich region of the Al–Mn–Ni alloy system were studied at 1000, 950, 850, 750, 700, 645 and 620 °C. Three ternary thermodynamically stable intermetallics, the φ-phase (Al 5 Co 2 -type, hP26 , P6 3 / mmc ; a = 0.76632(16), c = 0.78296(15) nm), the κ-phase (κ-Al 14.4 Cr 3.4 Ni l.1 -type, hP227 , P6 3 / m ; a = 1.7625(10), c = 1.2516(10) nm), and the O-phase (O-Al 77
