Abstract

Porosity formation during solidification in equiaxed microstructure of multicomponent nickel aluminide IC396M is examined. Two types of porosities are identified and related to the other scales of microstructure that evolve during solidification. A correlation is established between the relevent processing parameters and the microstructure variables.
