Embodiment 1

[0040] According to the high-strength alloy composition is Cu 63 mn 30 Al 5 Ni 10 Preparation of alloy raw materials. The prepared alloy raw materials were put into a melting furnace for melting. During the melting process, 99.999% high-purity argon gas was introduced, the pressure was 0.5 atmospheres, and the temperature was smelted at 1200°C for 40 minutes. Then it was refined at a temperature of 1100° C. for 30 minutes, and finally cast into alloy ingot A1.

Embodiment 2-21

[0042] Alloy ingots A2-A21 were prepared according to the method of Example 1, with the difference that: alloy raw materials were prepared according to Table 1.

Abstract

The invention provides a high-strength alloy and a preparation method thereof. Taking the total amount of the alloy as a standard, the alloy contains the following elements in weight percent: 21-40% of Mn, 3.1-15% of Al, 45-75.9% of Cu, and 5-20% of Ni. The alloy disclosed by the invention is high in strength and low in cost, has excellent corrosion resistance and good castability, cannot easy generate crack during casting, and is high in mechanical strength, good in toughness and good in corrosion resistance.

Description

technical field [0001] The invention belongs to the field of alloys, in particular to a high-strength casting alloy. Background technique [0002] With the rapid development of product technology represented by electronic products and automobiles, products are becoming more sophisticated and miniaturized, which puts forward higher and higher requirements for the performance and casting characteristics of materials. Aluminum alloy, magnesium alloy and zinc alloy are rich in raw materials and have excellent casting performance. They have become the main structural materials for the production and life of the national economy, but their mechanical strength is low. Although high-strength materials have also been developed, the processing and manufacturability of materials is greatly improved. Reduced, and therefore more and more restricted in some demanding product areas. [0003] Due to the advantages of light weight, high strength, and good corrosion resistance, titanium allo...
