Metal grains are formed in the liquid metal, and on the walls of the mold. As the liquid metal solidifies, dendrites are formed that are maintained even after the solidification of the casting. Other defects produced in the microstructure are inclusions, large voids, and pinholes in the casting due to the entrapped and soluble gases.
