Abstract

A method for improving the coordination of rolling deformation of titanium-magnesium clad plates by self-riveting configuration arrangement. The invention relates to a method for enhancing the connection strength of heterogeneous metal composite plates. The present invention aims to solve the uncoordinated deformation of plates with different strength and plastic deformation ability in the current rolling process of heterogeneous metal composite plates, which further causes dislocation, uneven deformation, cracking and welding rate of heterogeneous metal plates in the forming process of composite plates Low and produce waves and other problems. Methods: 1. Process prefabricated holes and grooves with a certain arrangement on the surface of the plate; 2. Clean the surface of the heterogeneous plate; 3. Roll the plate; 4. Subsequent heat treatment to remove residual stress. The invention is used to improve the coordination of rolling deformation of heterogeneous metal clad plates.

Description

technical field [0001] The invention relates to a method for improving the coordination of rolling deformation of heterogeneous metal clad plates through self-riveting configuration arrangement. Background technique [0002] With the continuous development of the fields of aerospace, ships, and national defense, the requirements for lightweight structures are constantly increasing, and the requirements for the comprehensive performance of metal structural materials are also increasing. Not only are metal structural materials required to be lightweight and high-strength, but also high rigidity, corrosion resistance, and shock absorption are required to achieve comprehensive performance. It is difficult for a single metal or alloy to meet such harsh requirements, and metal composite panels are an important way to solve this problem. For example, titanium alloy has the advantages of high specific strength, high specific stiffness and corrosion resistance, magnesium alloy has t...
