Problems solved by technology

It is precisely because of the excellent characteristics of aluminum bronze that it is becoming more and more popular and plays an important role in civil and military industries. The mechanical properties of materials refer to the ability of materials to withstand various conditions under different environments (temperature, medium, humidity). However, there are still various problems in the mechanical properties of various aluminum bronzes on the market.
[0003] For example, the authorized announcement number is CN107663598A, which discloses a manufacturing method of aluminum bronze, although it realizes reasonable quenching and tempering treatment of the formed aluminum bronze, so that the aluminum bronze has better wear resistance and corrosion resistance and heat resistance, and has better mechanical properties, which can be used to cast heavy-duty, corrosion-resistant and wear-resistant parts, but it does not solve the problem that the existing aluminum bronze contains dross and aluminum bronze cannot To achieve the problems of anti-corrosion, etc., we propose a method to improve the mechanical properties of aluminum bronze

Abstract

The invention discloses a method for improving the mechanical properties of aluminum bronze; it includes the following steps: S1, selecting metal materials; S2, hot-melting metal materials; S3, casting aluminum bronze ingots; S4, delaying the cooling of aluminum bronze ingots; S5, Aluminum bronze multi-stage forging; S6, aluminum bronze extrusion to remove oxidation surface layer; the present invention realizes increasing corrosion resistance to aluminum bronze by adding chromium, titanium and niobium in aluminum bronze, and adds zinc and nickel to increase aluminum bronze surface Glossiness, adding alkaline earth metal compounds during the hot melting process of aluminum bronze raw materials, to achieve adsorption and precipitation of dross in the aluminum bronze solution at the bottom of the furnace, to filter out the dross inside the aluminum bronze, and in the aluminum bronze solution When the ingot is not formed, a covering agent is added to connect the aluminum bronze and maintain the fluidity of the aluminum bronze surface, and multi-stage forging and quenching are used to maintain the compactness and stability of the aluminum bronze structure.

Description

technical field [0001] The invention belongs to the technical field of aluminum bronze, and in particular relates to a method for improving the mechanical properties of aluminum bronze. Background technique [0002] The copper-based alloy with aluminum as the main alloying element is an aluminum bronze containing iron and manganese elements, which belongs to high-strength heat-resistant bronze, and aluminum bronze has many excellent properties. Aluminum bronze has high strength, hardness and wear resistance, and is often used to manufacture gear blanks, threads and other parts. Aluminum bronze has good corrosion resistance, so it can be used to manufacture corrosion-resistant parts, such as propellers, valves, etc. Aluminum bronze does not spark under impact and can be used to make non-sparking tool materials. It has excellent thermal conductivity and stable rigidity. As a mold material, it will not cause mold sticking and scratch workpieces when stretching and rolling sta...
