A method for preparing Al-Pd-Fe two-dimensional quasi-crystal particles, the atomic ratio of the chemical composition of the Al-Pd-Fe quasi-crystal is: Al 70-75%, Pd 10-25%, Fe 5-15 %, fully and uniformly mix high-purity Al powder, Pd powder and Fe powder with a mortar, evenly distribute the mixed metal powder in the cavity of the graphite abrasive tool, pre-press on the mold tablet press, and keep 60 at 1-2MPa ‑100s, wrap a layer of carbon felt outside the graphite crucible, and then follow the steps of carbon paper, large graphite pad, carbon paper, small graphite pad, prepared graphite crucible, small graphite pad, carbon paper, large graphite pad, The carbon papers are sequentially placed in the pressure cavity of the SPS and pressed tightly, the sintering pressure is 50MPa, the temperature is raised to 1000-1100°C and kept for 10-20min, and then cooled to room temperature with the furnace. The invention has the advantages of simple process, strong operability, conventional equipment, less time consumption, and can directly use mixed raw materials to synthesize the two-dimensional quasi-crystal phase while reducing the treatment of raw materials.
