The invention relates to an endogenous micro-nano hybrid dual-phase ceramic particle strengthening agent and a method for strengthening an aluminum alloy, comprising the following three steps: (1) preparation of a micro-nano hybrid scale endogenous dual-phase TiC-TiB 2 ceramic particle strengthening agent; (2) Preparation of micro-nano hybrid scale endogenous dual-phase TiC-TiB 2 ceramic particles reinforced aluminum alloy; (3) Micro-nano hybrid scale endogenous dual-phase TiC-TiB 2 ceramic particles reinforced aluminum alloy hot extrusion plastic forming; ( 4) Heat treatment of the strengthened aluminum alloy. The technical solution involved in the invention has a significant effect of improving the high temperature performance of the aluminum alloy, and the addition of a small amount of particles can greatly enhance the high temperature performance, the steps are simple and the effect is obvious, and it is of great significance and value for the enhancement of the high temperature performance of the aluminum alloy material. |
