As an improvement, the rate of heat addition of the step 3 kind is 20 DEG C/min.
As an improvement, the heat treatment temperature of the step four is 600 DEG C -800 DEG C, heat treatment time is 20 min-
100min, heat treatment carry out under an inert gas.
As an improvement, the hot extrusion ratio of the step 5 is 20:1-8:Between 1, extrusion temperature is controlled at 500 DEG C -700
℃。
As an improvement, the heating temperature of the step 3 is 1500 DEG C -1600 DEG C, and then the size controlling of chromium carbide is existed
Preferably horizontal, further preferably heating temperature is 1550 DEG C.
As an improvement, it is 25%-30% that carbon black, which accounts for enhancing phase raw material weight, in the step one, in this preferable case
Under, the chromium carbide obtained in the original location among generating process is more fine and close, reaches Nano grade, and can be fully dispersed to base
Among body material.
Composite material disclosed by the invention is applied in aluminium alloy 3D printing field, enables to the properties of product printed
Achieve the effect that forging, and existing is typically the performance for being not achieved forging.
Chromium carbide enhancing mutually can reach Nano grade, the simple joint bone of preparation in aluminum matrix composite disclosed by the invention
Clamp light and portable, this nano ceramics aluminium alloy is light-weight, and with high rigidity, high intensity, antifatigue, low bulk, high-damping,
The features such as high temperature resistant, compared to titanium alloy and high temperature alloy, can significantly increase the dimensional stability of simple joint bone forceps.
