【Abstract】 Foam Aluminum is a material of absorbing sound. In this paper, we used the method of penetrating casting to form the foam Al - alloys. The effects of die temperature, preheating temperature of granules and pouring temperature on the forming process of penetrating costing were systematically studied, the distribution of forming pressure was theoretically analysed and the effect of the forming pressure on the casting quality was discussed.更多还原
