Abstract

The invention discloses an alloy material with high comprehensive performance and a preparation method thereof. The alloy material consists of the following components in percentage by weight: 9-12% of Si, 0.4-0.7% of Fe, 1-3% of Cu, 0.004-0.006% of Au, 0.6-0.8% of Mg, 0.4-0.7% of Pd, 0.5-0.8% of Ni, 2-6% of Zn, 1-4% of Sr, 0.2-0.5% of Ho and the balance Al. Solute atoms dissolved into a solid solution increase the strength and hardness of an alloy solid solution so that the alloy material has good stability, practicability and mechanical properties. The preparation method adopts zone meltingto introduce a Pd-Ho crystal phase, so that the plasticity of an amorphous alloy is significantly improved. Due to the forging and heat treatment technologies after casting, the microstructure and themechanical properties of the alloy material are improved, and the alloy material has relatively high comprehensive performance.

Description

technical field [0001] The invention belongs to the field of aluminum alloy materials, and in particular relates to an alloy material with high comprehensive performance and a preparation method thereof. Background technique [0002] According to the arrangement of atoms, substances can be divided into two categories: crystalline and amorphous. When the atomic arrangement of the material is regular and orderly, it is a crystalline material. Otherwise, the atomic arrangement is irregular and it is amorphous. When the atomic arrangement structure of a solid alloy is similar to that of a liquid metal, it is called an amorphous alloy when it is a long-range disordered state. The amorphous state can be obtained by not crystallizing during the cooling process of the substance, and can also be prepared by vapor phase deposition, ion beam mixing and other methods. Amorphous alloys are different from traditional oxide glasses. Atoms in amorphous alloys are connected by metal bonds r...
