 · In particular, significant grain refinement was reported for electromagnetic stirring while applying rotating magnetic fields (RMFs) in Sn-Pb alloys, Al-based,, and Al-Cu alloys. Campanella et al. used a pulsating magnetic field in Cu-based alloys and suggested a simple criterion for fragmentation induced by fluid flow on the basis of the Cited by: 2. Lim et al.

During solidification of Ti46Al6NbB by cold crucible, Yang et al. found the electromagnetic stirring could not only restrict micro-segregation to yield uniform solute distribution, but also hinder the formation of columnar grains and thus induce grain refinement. The electromagnetic cold crucible is planned to continuously solidify the. 2 Grain Refinement by Vibration and Stirring (VS) Stirring and vibration during solidification are widely used for grain refining of aluminum. Various stirring methods were developed, including mechanical stirring, electromagnetic stirring and bubble mixing [48, 49, 50].

Electromagnetic Stirring. Electromagnetic stirring is a technique commonly used industrially in the grain refinement of steel and copper alloys. It has also been found to be effective in the grain refinement of Al- and Mg-based alloys. Lim et al. Effect of magnetic stirring on grain structure refinement: Part 2. Science and Technology of Welding and Joining VOL NO 4. to increase the solidification range of the weld. To obtain a large-sized, high-quality aluminum alloy billet, an advanced uniform direct chill (UDC) casting method was developed by combining annular electromagnetic stirring (A-EMS) with intercooling in the sump. The alloy was chosen to investigate the effect of UDC on grain refinement and homogeneity during normal direct chill (NDC) casting. It was concluded that the microstructure.
