Uniform post-treatment method for steel and aluminum 4 graphite solid-liquid phase 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.

[0001] The invention relates to a post-treatment method of rolling at room temperature for the interfacial shear strength of a steel-aluminum-graphite solid-liquid phase composite plate. Background technique

[0002] Publication No.: CN1710114A, Invention Name: "A post-treatment method for steel-backed aluminum-based solid-liquid phase composite plate", described the room temperature rolling post-treatment method for steel-backed aluminum-based solid-liquid phase composite plate, that is, at room temperature Next, in the precision rolling mill, the steel-backed aluminum-based solid-liquid phase composite plate is subjected to post-rolling treatment, and the difference in deformation between the aluminum-based cladding and the steel back produced by the rolling treatment is used to compensate for the deformation of the aluminum-based composite plate during the composite solidification and cooling process. The difference in shrinkage between the cladding and th...
