Homogenizing post-treatment method of steel aluminum-7-graphite solid-liquid composite board

Abstract

The invention discloses a homogenizing post-treatment method of a steel aluminum-7-graphite solid-liquid composite board and belongs to the research field of the steel aluminum-7-graphite solid-liquid composite board interfacial shear strength room temperature rolling post-treatment. The method is as follows: two-pass rolling treatment is performed on a steel aluminum-7-graphite solid-liquid composite board composed of a 08Al steel plate of which the thickness is 1.2mm and an aluminum-7-graphite coating layer of which the thickness is 2.0mm on a precision rolling mill at the room temperature under the conditions that total reduction rate is 1.5% and the pass reduction rate ratio of the first pass to the second pass is (1:4)-(1:2). The shear strength difference of the transverse interface of the composite board can be reduced to less than 2Mpa.

Description

technical field [0001] The invention relates to a post-treatment method of rolling at room temperature for the interfacial shear strength of a steel-aluminum-7-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 ...
