Abstract

The semi-solid A380 aluminum alloy slurry prepared by water-cooling serpentine channel and its rheo-diecasting were studied in this paper. The result showed that the pouring temperature and cooling water flow rate had a significant effect on the semi-solid slurry. When the pouring temperature decreased from 670 to 610 °C, the average grain diameter and shape factor of the primary α-Al grains decreased from 64 to 47 µm and increased from 0.74 to 0.82, respectively, but the mass of semi-solid slurry blocked in channel increased. With the cooling water flow rate increasing from 0 to 1000 L/h, the semi-solid slurry firstly got optimized and then deteriorated. Under the condition of the same die casting process parameters, the rheo-diecastings produced by the semi-solid slurry prepared through water-cooled serpentine channel had higher mechanical properties than those of the traditional die castings.

Graphic Abstract

In this work, a new simple and low cost preparation of semi-solid slurry was invited, which was suitable for rheological forming of the short process. What's more, the rheo-diecasting was studied through comparing the traditional die casting. The result showed that the pouring temperature and cooling water flow rate had a significant effect on the semi-solid slurry. When the pouring temperature decreased, the average grain diameter and shape factor of the primary α-Al grains increased and decreased respectively. With the cooling water flow rate increasing, the semi-solid slurry firstly got optimized and then deteriorated. Under the condition of the same die casting process parameters, the rheo-diecastings produced by the semi-solid slurry prepared through water-cooled serpentine channel had higher mechanical properties than those of the traditional die castings.
