Embodiment Construction

[0063] The present invention will be further described below in conjunction with accompanying drawing:

[0064] figure 1 As shown in the figure, it is the smelting state diagram of the quasi-crystal reinforced aluminum matrix composite material. The position of each part must be correct, and the operation should be carried out in sequence.

[0065] The amount of chemical substances used in the preparation is determined according to the pre-set range, in grams, milliliters, centimeters 3 is the unit of measurement.

[0066]The smelting of quasi-crystal enhanced aluminum matrix composites is carried out in the intermediate frequency induction melting furnace, which is completed in the process of intermediate frequency induction heating, vacuuming, argon bottom blowing, and casting; the intermediate frequency induction melting furnace is vertical, and the intermediate frequency The bottom of the induction melting furnace 1 is the furnace seat 2, and the inside is the furnace ch...

Abstract

The invention relates to a preparation method of a quasi-crystal reinforced type aluminum-based composite material. Aiming at a condition that the aluminum-base material has low hardness, low tensile strength and bad corrosion resistance, the preparation method comprises the following steps: smelting in a vacuum smelting furnace, performing argon gas bottom-blowing protection, casting and extruding by using the aluminum alloy as a matrix and taking aluminum copper iron quasi-crystal as an enhancer. The preparation method is advanced in process, strict in procedure and precise and accurate in data. The prepared quasi-crystal enhanced aluminum matrix composite material has hardness up to 82.6 HB which is increased by 61.33%, tensile strength up to 283Mpa which is increased by 74.75%, and corrosion resistance is increased by 30%. The preparation method is an ideal preparation method of the quasi-crystal reinforced type aluminum-based composite material.

Description

technical field [0001] The invention relates to a method for preparing a quasi-crystal reinforced aluminum-based composite material, which belongs to the technical field of preparation and application of non-ferrous metal materials. Background technique [0002] Aluminum alloy is a non-ferrous metal alloy with good strength, toughness, electrical and thermal conductivity. It is often used as a structural material and has been widely used in aerospace, electronics industry, and automobile manufacturing. Low strength and poor corrosion resistance limit its industrial application. [0003] Quasicrystal is a solid-state ordered phase with long-range quasi-periodic translation order and amorphous rotational symmetry. Quasicrystal material has defects of brittleness and loose metallographic structure, so it is difficult to be used as structural material, but quasicrystal has high The comprehensive properties of hardness, non-stickiness, low expansion coefficient, wear resistance,...
