ABSTRACT:
A method for the manufacture of a highly ductile material comprises melting an alloy material in a crucible held under a vacuum, inserting a stirring bar in the molten alloy material in the crucible and rotating the stirring bar at a low speed, causing the stirring bar to be rotated at a high speed after the molten alloy material has reached the temperature for starting solidification, and continuing the high speed rotation of the stirring bar until immediately before completion of the solidification.
