发展了一种新的方法,即“部分熔化强化法”,用这种新的方法成功地生产了高强和高韧性的变形铝合金。采用这种方法时,铸锭含有溶质的数量要大于最终要求的数量,该铸锭在陶瓷过滤器上面承受适当的压力,并且同时加热到固相线以上。当产生部分熔化时,液体便从枝晶间挤出,并通过过 Developed a new method, the “partial melting strengthening method”, with this new method successfully produced high strength and high toughness of the deformed aluminum alloy. In this method, the ingot contains more solute than the final amount required, the ingot is subjected to appropriate pressure on the ceramic filter and heated above the solidus. When the partial melting occurs, the liquid is squeezed out of the dendrite and passed
