The Product Process of Rheology Material for Grain Size Control by Electromagnetic Stirring

Actual trends in automotive industry lead to an increase use of lightweight structures imposing the need for high strength aluminum alloys with complex shape. In the electromagnetic stirring process, it has many merits which are the exact control ability about material processing and a good point of the protection of environment comparison with the mechanical stirring. The interface of cells consisting of primary particle formed by the electromagnetic stirring due to particle regrowth during cooling the alloy. By electromagnetic stirring process, the microstructure of material has a good point, also it can control the material processing exactly.
