Abstract

The invention relates to a preparation method of an aluminum-based composite material with controllable reinforcement phase distribution, which belongs to the technical field of preparation of aluminum alloy composite materials, solves the technical problem that reinforcement phases in the aluminum-based composite material are difficult to control, and adopts the technical scheme as follows: 1, an aluminum oxide film self-generated on the surface of an aluminum alloy is used as the reinforcement phases; 2, the layered structure is utilized to improve the distribution of the reinforcement phase, and different layer numbers are used to control the layered distribution of the reinforcement phase; 3, the integrity of an aluminum oxide film in the layered structure material is damaged through hot pressing welding and corrugated rolling, different compression amounts or rolling speeds and states are used, the oxidation film between layers is broken, and fresh molten metal leaks to promote combination of layered metal; and 4, the distribution state of the layered fragmentation oxidation film is changed through multidirectional compression, and the high-performance aluminum-based composite material with the controllable reinforcement phase distribution is obtained. The multi-layer non-uniform layered composite structure is substantially a multi-layer non-uniform layered composite structure combining ultra-fine grains and coarse grains, the improvement of the strength and plasticity in a traditional mode is surpassed, and the improvement of the material safety is facilitated.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy composite material preparation, and in particular relates to a method for preparing an aluminum matrix composite material with controllable reinforcement phase distribution. Background technique [0002] Although aluminum matrix composites have excellent properties, there are still many difficulties in the preparation of composites. Because the wetting angle between the matrix aluminum alloy and the reinforcement phase particles is generally large, the combination is difficult, and the preparation process is also varied. In the traditional casting process, the addition and integration of the particle phase is not easy to carry out. The metal composite materials prepared by conventional methods appear in the form of impurities in the matrix, and their mechanical properties are not as good as those of the matrix material, especially nano-scale. Reinforcement phase particles, the particles ha...
