Abstract

The invention relates to a method for preparing a metal matrix composite under different composite pressures in a high-throughput manner, particularly relates to the method for preparing the metal matrix composite under the different composite pressures, aims to solve the problem that high-throughput preparation of the metal matrix composite under the different composite pressures cannot be achieved. The method comprises the following steps that tandem type prefabricated bodies are concentrically and annularly hoisted on the lower surface of a prefabricated body mounting disc, and a crucible is filled with matrix metal; the same composite reinforcements fill all molds in each tandem type prefabricated body, and different composite reinforcements fill the different tandem type prefabricatedbodies correspondingly; and the pressure is changed, and infiltrating is sequentially carried out on the lower molds in the tandem type prefabricated bodies. According to the method, the tandem typeprefabricated body molds are used for preparation of the metal matrix composite or a test sample with different infiltration pressures and the different reinforcements in the high-throughput manner, so that the interface wetting and interface reaction behaviors of the composite can be efficiently studied. The method is suitable for obtaining the infiltration behavior of the metal matrix compositeunder the different pressures.

Description

technical field [0001] The invention relates to a method for preparing metal matrix composite materials under different composite pressures. Background technique [0002] The pressure infiltration method is to apply pressure on the matrix metal melt through mechanical devices or high-pressure gas, so that it can forcibly break through the surface tension of the preform and other infiltration resistance to penetrate into the void of the reinforcement preform. Due to the infiltration and flow under high pressure, the surface tension between the reinforcement and the matrix is ​​overcome, and the non-wetting composite material system can also be wetted under high pressure. In some cases, the gap between the reinforcement particles is nanometer to micrometer, but it can also be composited with high quality, which has become the most ideal method for preparing high-strength and high-quality metal matrix composites. [0003] The current literature and patented technologies are al...
