Abstract

The invention relates to a preparation method for an endogenous nano-sized particle reinforced aluminum alloy material. The preparation method comprises the following steps that (1) a pressing blank is prepared; (2) endogenous nano TiC particle reinforced alloy is prepared through in-situ reaction; (3) thermal extrusion forming is conducted; and (4) thermal treatment is conducted. According to the technical scheme of the preparation method, nano-sized ceramic particles are brought into metal, the nano-sized ceramic particles are generated in the metal in an endogenous mode through the in-situ endogenous technology and are evenly dispersed, and the nano particle reinforced aluminum alloy material with evenly-dispersed multi-content-conversion reinforced phases from the low volume fraction to the high volume fraction is obtained; and the material has ultra-high obdurability and important practical application value.

Description

technical field [0001] The invention relates to the field of aluminum alloy processing, in particular to a method for preparing an aluminum alloy material reinforced with endogenous nanometer-sized particles. Background technique [0002] With the increasingly high requirements for materials in the fields of energy, automobiles, aviation, aerospace and communication information, traditional materials can no longer meet the actual requirements. For example, in the fields of aviation and aerospace, materials are required to have higher stiffness and lower coefficient of thermal expansion; in the automotive industry, materials are required to be lighter in weight, higher in strength and toughness, better in stability and stronger in wear resistance. In order to meet the above-mentioned unique performance requirements for materials, particle-reinforced aluminum alloy materials have gradually entered people's sight because of their low cost, low density, high elastic modulus, hig...
