Abstract

The morphological transition and growth mechanism of Al₃Ni phase during solidification at the liquid Al/solid Ni interface was investigated through synchrotron radiography. The remelted peritectic Al₃Ni is dominated by coalescence of adjacent grains and precipitation with the morphology changing from columnar, irregular, scallop type to faceted shape. The hollow proeutectic Al₃Ni is formed on a solid base. The increased r/R ratio and steep variation lead to the change from regular to irregular hollowness with asymmetrical shape.
