Problems solved by technology

Composite materials with the same volume ratio and particle ratio can be prepared by this method, but it cannot meet the different requirements of different engineering applications for the volume ratio of composite materials strengthening particles, so it also limits the molding application field of composite materials
[0004] Therefore, if the preparation of the current high-strength particle-reinforced aluminum-based composite materials is to be applied in the field of automobile manufacturing, there are still the following problems that need to be overcome: the price of fiber reinforced materials is high, the structure is unstable, the comprehensive performance is low, and the compatibility of composite materials is low. The field of use is limited

Embodiment 1

[0027] Take 1Kg of alloy powder prepared according to the mass ratio of the following components: 60% aluminum, 20% magnesium, and 20% copper, then mix the alloy powder with 250g of titanium boride particles, and place the mixed powder in a square die-casting mill After die casting with an injection specific pressure of 40kPa, the filling speed is 20m / s, and then the above pressure cast preform is heated to 400°C under the protection of nitrogen for 3 hours, and then cooled again The preformed billet is subjected to pressure casting to obtain a molded billet. The compression specific pressure of the die casting is 70KPa, and the filling speed is 50m / s. Finally, place the molded block under the protection of nitrogen and heat it to 600°C, keep it warm for 3 hours, then cool it down to normal temperature, and take it out.

Embodiment 2-3

[0029] Repeat the same steps as described in Example 1, but in Example 2, the alloy powders in Example 3 are formed according to the mass ratio of the following components: 50% aluminum, 20% magnesium, and 30% copper; Aluminum 70%, Magnesium 10%, Copper 20%.

Embodiment 4-5

[0031] Carry out embodiment 1 repeatedly by described same procedure, but the quality of the titanium boride in embodiment 4,5 is respectively 33.3g, 20g.

Abstract

The invention relates to an aluminum-based composite material preparation method and an application thereof. The aluminum-based composite material is the high strength composite material which has the advantages of high cost performance, stable organization structure, high comprehensive property, high composite material compatibility, and wide usage field, the material is used for the furniture manufacture field, and is especially used for preparing a high load roller wheel. According to the invention, aluminium, magnesium and copper are taken as alloy powder, titanium boride is taken as reinforcement particles, steps of mixing, reinforcing, pressure casting are carried out, and then thermoforming mould, semisolid casting and heat treatment are performed to obtain the high strength aluminium-based composite material.

Description

technical field [0001] The invention relates to the technical field of metal composite materials, in particular to a high-strength aluminum-based composite material, its preparation method and its application. Background technique [0002] In the automobile manufacturing industry with continuous improvement in specific performance, increasing environmental protection requirements, and increasingly fierce cost-effective competition, new high-performance metal composite materials are used. Aluminum-based composite materials have high specific strength, high specific modulus, high temperature resistance, wear resistance and thermal expansion. Excellent physical and mechanical properties such as small coefficients have been widely used in the manufacture of daily necessities, automobiles, electronic instruments, and even aerospace and national defense. The development of high-strength particle-reinforced composite materials is an inevitable trend for composite materials to be wi...
