Experimental investigation of phase equilibria in the Al–Ni–Sc system
Phase equilibria in Al–Ni–Sc ternary system have been measured through alloy sampling. According to the results from electron probe microanalysis and X-ray diffraction techniques, isothermal sections of Al–Ni–Sc ternary system at 1173 K and 1273 K were constructed, where four new ternary phases, τ7...

Summary: | Phase equilibria in Al–Ni–Sc ternary system have been measured through alloy sampling. According to the results from electron probe microanalysis and X-ray diffraction techniques, isothermal sections of Al–Ni–Sc ternary system at 1173 K and 1273 K were constructed, where four new ternary phases, τ7 (Ni
