摘要

Series of experiments on a series of Al-Fe-Mg alloys were performed to determine the effect of rapid solidification (RS) on the material strengthening, which result from the refining of the grain size and intermetallic compound. Additionally, an enhancement of the material strengthening due to magnesium addition was also observed. Manufacture of RS Al-Fe-Mg alloys combined a spray deposition of the molten alloy on the rotating water-cooled copper roll and plastic consolidation by means of powders pressing and hot extrusion methods. The results suggest that the rapid solidification provides an effective method of microstructure refinement and, in combination with solid solution hardening due to Mg, leads to significant improvement of mechanical properties of Al-Fe-Mg based alloys.
