Abstract

The invention discloses a homogenization post processing method for a steel aluminum 9 graphite semisolid composite board, belonging to the field of research on rolling post processing of the steel aluminum 9 graphite semisolid composite board at room temperature for interface shear strength . In the method provided by the invention, two-pass rolling processes are carried out on the aluminum 9 graphite semisolid composite board formed by a 08A1 steel plate the thickness of which is 1.2mm and an aluminum 9 graphite layer the thickness of which is 1.0mm by a rolling mill at room temperature, wherein the total down rate is 0.7% and the down rate ratio of the primary rolling process to the secondary rolling process is (1:2.5)-(2:1), and the transverse interface shear strength difference of the composite board is reduced below 1.7MPa.

Description

technical field [0001] The invention relates to a method for post-processing the interface shear strength of a steel-aluminum-graphite semi-solid composite plate after rolling at room temperature. Background technique [0002] Publication No.: CN101117696A, Invention Name: "A post-treatment method for steel-backed aluminum-based semi-solid composite board", expounds the room-temperature rolling post-treatment method for steel-backed aluminum-based semi-solid composite board, that is, at room temperature, In the precision rolling mill, the steel-backed aluminum-based semi-solid composite plate is processed after rolling, and the difference in deformation between the aluminum-based coating and the steel back produced by the rolling treatment is used to compensate for the difference between the aluminum-based coating and the steel back during the composite solidification and cooling process. The difference in the shrinkage of the steel back reduces the additional stress on the ...
