Homogenizing

Ingots in some alloys are heat treated, homogenized, to improve strength and moldability of the final product.

Homogenization changes the  of the microstructure resulting from casting. The type of mixed crystals formed during solidification have varying contents. The homogenization of the material equalize the material properties so that a consistent, homogeneous microstructure is obtained in the material.
