| Abstract: | The influence of electromagnetic stirring on the solidification structures of the spring steel castings or ingots has been investigated. The experiments have shown that the large columnar dendric austenitie formed in a conventional unstirred castings can be substituted by fine equiaxed grains or dedendric grains when stirred with electromagnetic field for a short time. The higher stirring power, the more spherical or dedendritic the austenite was obtained. The amount of austenite nucleation increased and austenite grain become finer in stirring castings. |
