Embodiment Construction

[0008] A uniform post-processing method for steel-aluminum 4 graphite solid-liquid phase composite plates. At room temperature, on a precision rolling mill, the steel-aluminum 4 graphite composed of a 1.2mm thick 08Al steel plate and a 1.0mm thick aluminum 4 graphite coating The solid-liquid phase composite board is subjected to two-pass post-rolling treatment with a total reduction ratio of 1.7%, and the large difference in the amount of lateral deformation of the aluminum 4 graphite coating produced by the single-pass high-reduction rolling post-treatment, Decomposed and coordinated into the small difference in the lateral deformation of the aluminum 4 graphite coating produced by the two-pass low reduction ratio rolling, thereby further reducing the difference in the transverse interface shear strength of the composite plate, and improving the solidity of the steel aluminum 4 graphite The distribution uniformity of the interface shear strength of the liquid composite plate.

Abstract

The invention discloses a uniform post-treatment method of a steel and aluminum 4 graphite solid-liquid phase composite plate, which belongs to the field of research on interfacial shear strength room temperature rolling post-treatment of the steel and aluminum 4 graphite solid-liquid phase composite plate. In the method, two-pass rolling treatment is performed on the steel and aluminum 4 graphite solid-liquid phase composite plate which is composed of a 08Al steel plate with the thickness of 1.2mm and an aluminum 4 graphite covering layer with the thickness of 1.0mm on a precision rolling mill at room temperature, wherein the total reduction rate is 1.7%, and the proportion of the pass reduction rate of a first pass to the pass reduction rate of a second pass is 1: 5-1: 3, and the transverse interfacial shear strength difference value of the composite plate can be reduced to 2.1MPa or less.

Description

Technical field [0001] The invention relates to a method for processing the interface shear strength of a steel-aluminum 4 graphite solid-liquid phase composite plate after rolling at room temperature. Background technique [0002] Publication number: CN1710114A, title of the invention: "A post-treatment method for steel-backed aluminum-based solid-liquid-phase composite board", the post-treatment method of steel-backed aluminum-based solid-liquid-phase composite board at room temperature is described, that is, at room temperature Next, on the precision rolling mill, the steel-back aluminum-based solid-liquid-phase composite plate is subjected to post-rolling treatment, and the difference between the aluminum-based coating and the steel back deformation produced by the rolling process is used to compensate for the aluminum-based composite solidification cooling process. The difference in shrinkage between the cladding and the steel back reduces the additional stress at the interf...
