Method for improving mechanical property of aluminum bronze

Abstract

The invention discloses a method for improving the mechanical property of aluminum bronze. The method comprises the following steps that S1, a metal material is selected; S2, the metal material is subjected to hot melting; S3, aluminum bronze ingot casting is carried out; S4, aluminum bronze cooling ingot casting is slowed; S5, aluminum bronze multistage forging is carried out; and S6, the aluminum bronze is extruded to remove an oxidation surface layer. According to the method, chromium, titanium and niobium are added into the aluminum bronze, so that the corrosion resistance of the aluminumbronze is increased; zinc and nickel are added, so that the glossiness of the surface of the aluminum bronze is increased; alkaline earth metal compounds are added in the hot melting process of an aluminum bronze raw material so that slag in an aluminum bronze solution can be adsorbed and precipitated at the bottom of a smelting furnace, and then the slag in the aluminum bronze can be filtered andremoved; when the aluminum bronze solution is not subjected to ingot casting forming, a covering agent is added, so that the connection of the aluminum bronze is achieved and the fluidity of the surface of the aluminum bronze is kept; and multistage forging and quenching are adopted, so that the compactness and stability of an aluminum bronze structure are kept.

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...

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
