Abstract
The present invention provides an aluminium alloy refiner. The aluminium alloy refiner is characterized by comprising 7 to 10 parts of Ti, 2 to 3 parts of B and the balance of Al by weight, for example, 8 parts of Ti, 3 parts of B and 89 parts of Al by weight. The aluminium alloy refiner is prepared by rapid solidification. After the refiner is added to A356.2 aluminium alloy, the grain size of the alloy is significantly reduced than that of the aluminium alloy treated by a conventional refiner. Moreover, the solubility of metals in liquid may be increased due to rapid solidification, such that the refiner is more easily absorbed by the aluminium alloy melt after being added to the aluminium alloy.
