| Abstract: | The batch preparation of A356 alloy foam slabs with various thicknesses (500×1000×X) was realized by melt foaming process. The key technologies of the process, including melt thickening, blowing agent adding and the foam uniformity controlling were systematically studied. The optimized process parameters for preparing A356 alloy foam blocks and slabs under factory conditions were obtained. The reasons of defects, such as under foaming, over foaming, big hole at center and crack, were investigated and the corresponding countermeasures were discussed. |
