Embodiment 1
[0050] A method for preparing a core-shell structure particle reinforced aluminum matrix composite material, the method steps are as follows:
[0051] (1) Add 0.15g Ti powder and 14.85g Al powder into the ball mill tank of SM-QB planetary ball mill, and add grinding balls and excess absolute ethanol according to the ball-to-material ratio of 0.5:1; at a speed of 600r / min , ball milled for 0.5h, and mixed evenly to obtain a mixed slurry; the mixed slurry was poured into a vacuum rotary evaporator, and the rotation speed was 100r / min, and the temperature of the water bath was 80°C, and then steamed for 0.2h, and after the ball milling medium was volatilized, the obtained Mixing the powder precursors; putting the mixed powder precursors into an electrothermal constant-temperature blast drying oven, and drying at 60° C. for 1 hour to obtain mixed powders.
[0052] Wherein, the grinding ball is composed of a large agate ball and a small agate ball with a mass ratio of 0.1:1, the di...
