Abstract: Methods for producing pigs made of a metal alloy, wherein initially a melt is formed in which a basic material and one or several alloy components are present in the liquid state, from which the pigs are formed. In the course of cooling, energy in the form of a variable field, which increases the formation of mixed crystals, is briefly introduced into the melt prior to the formation of the pigs. A pig thereby produced is a cast piece formed from a basic material and one or several alloy components and has been formed from a melt into which energy had been briefly introduced by a variable physical field in order to increase mixed crystal formation.
