ABSTRACT:
An alloy melt having a solidified portion of primary crystals is maintained at a temperature between solidus and liquidus temperature of the alloy. The primary crystals are molded to give individual degenerated dendrites or cast grains of essentially globular shape and hence impart thixotropic properties to the liquid-solid metal alloy phase by the production of mechanical vibrations in the frequency range between 10 and 100 kHz in this liquid-solid metal alloy phase.
