Abstract:
The problem that the micro-glassball is not wettable in molten aluminium alloys can be solved by a special technology that is different from rheocasting and squeezecasting methods. The metten metal can fill the cavity of the glass ball through the broken place on its wall, and an original micro -structure will be formed. This material has good comprehensive mechanical proper ties and this method can be used to other kinds of ceramic powders. The mechanisms of the formation of this materials have been discussed as well.
