Abstract
In order to refine the precipitate and grain, the combination of melt spinning and spark plasma sintering were used to prepare Al-11La-6Mg alloy. The results show that melt spun ribbon consists of some coarse precipitates. After spark plasma sintering, there are dual-scale precipitates in the matrix. As a result, the alloy exhibits a high compressive strength of 933 MPa and strain of 34% at room temperature. Unfortunately, the strength, at 300°C, is inferior to as-cast sample due to the fine grain.
