Abstract (en)
[origin: WO2016144274A1] The present invention relates to a method for grain refining in aluminum alloys. In order to achieve a successful grain refinement, the method described herein depends on two major steps, first the addition of enough Sr to molten aluminum alloy then the addition of enough B to the mixture after the flux fades out during the degassing process while rotor is still rotating.
