Embodiment Construction

[0061] The present invention will be further described below in conjunction with accompanying drawing:

[0062] figure 1 As shown in the figure, in order to prepare the aluminum-copper-iron alloy state diagram for smelting, the position and connection relationship of each part must be correct, the ratio should be proportioned, and the operations should be performed in sequence.

[0063] The amount of chemical substances used in the preparation of smelting is determined according to the preset range, in grams, milliliters, centimeters 3 is the unit of measurement.

[0064] The smelting and preparation of aluminum-copper-iron alloy is carried out in the intermediate frequency induction melting furnace, which is completed in the process of intermediate frequency heating smelting, vacuuming, argon bottom blowing, and casting;

[0065]The intermediate frequency induction melting furnace is vertical, the bottom of the intermediate frequency induction melting furnace 1 is the furna...

Abstract

The invention relates to a preparation method of an aluminum, copper and iron quasicrystal. In order to solve the problem that process defects exist as the preparation method of the aluminum, copper and iron quasicrystal is difficult, the preparation method comprises the following steps: smelting and casting, quickly cooling, thermally treating and annealing and quenching to prepare an aluminum, copper and iron quasicrystal block material by adopting a medium-frequency induction smelting furnace casting method. The preparation method of the aluminum, copper and iron quasicrystal disclosed by the invention is advanced in process, accurate and full in data; the I phase of the quasicrystal is Al61.92Cu26.21Fe11.87, the product purity is high, the I phase content of the quasicrystal is 98%, the mechanical performances are stable, the hardness is 796HV, and therefore, the preparation method can be applied to various industrial fields and is a very ideal preparation method of the aluminum, copper and iron quasicrystal.

Description

technical field [0001] The invention relates to a method for preparing an aluminum-copper-iron quasicrystal, belonging to the technical field of metal material preparation and application. Background technique [0002] A quasicrystal is a solid-state ordered phase with long-range quasi-periodic translational order and amorphous rotational symmetry; among the known quasicrystals, only a few are in a thermodynamically stable state, and Al-Cu-Fe quasicrystals are One of them: Al-Cu-Fe quasi-crystal particles have high hardness, low thermal expansion coefficient, high elastic modulus, and excellent corrosion resistance properties. They are suitable for the reinforcement phase of soft substrates and have good application and development prospects. [0003] At present, the preparation methods of quasicrystals include gas atomization method, belt throwing method, falling tube solidification method, and electromagnetic levitation melting method. However, these methods have technical...
