Description
Summary:The Al-based alloy with equiaxed grains was directly produced in the industrial aluminum electrolyzer. The varieties of grain features and grain sizes vs the re-melting times of this alloy were investigated. The grain features and mechanical properties of A356 alloy made from this alloy during the several re-melted times were also studied. The results show that the Al-based alloy after re-melted for 6 times, and A356 after re-melted for 3 times, both remained and refined grains and A356 alloy could achieve favorable mechanical properties. All these should be attributed to the electrolyzing procedure, in which nucleates, such as Al3Ti, are distributed fully and even in the based alloy. Producing Al-based alloy in the industrial electrolyzer provides a new, efficient and practical grain-refining route.
