| Abstract: | The effects of preheating temperature of granules,pouring temperature of melt and forming pressure on the forming process of penetrating casting of foam Al- alloys around granules were systematically studied using orthogonal experiment method and choosing three kinds of the granules size and the experimental results were theoretically analysed.It is consid- ered that the reasonable selection of granules preheating temperature is a prerequisite to produce the foam metal castings,proper increase of pouring temperature is a key to achieve the homoge- neous foam construction and the moderate forming pressure can increase the product porosity and technological stability. |
