Abstract

The invention discloses a uniform post-processing method of a steel titanium bronze 3.5-4 graphite semi-solid composite plate, belonging to the research field of interface shear strength room-temperature rolling post-processing of the steel titanium bronze 3.5-4 graphite semi-solid composite plate. In the invention, two passes of rolling processing are carried out on the steel titanium bronze 3.5-4 graphite semi-solid composite plate formed from a 08Al steel plate with the thickness of 1.2mm and a titanium bronze 3.5-4 graphite coating with the thickness of 2.8mm on a finishing mill at the room temperature with the total reduction of 1.0 percent and the percentage pass reduction ratio of a first pass and a second pass of 1:4.5-1:2.5, and the transverse interface shear strength difference of the composite plate is lowered within 2.0MPa.

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 titanium bronze 3.5-4 graphite semi-solid composite plate. Background technique [0002] Publication number: CN1916193A, title of invention: "A Method for Reducing the Residual Stress at the Interface of Steel-Copper-Graphite Composite Plate", expounds the room temperature rolling post-treatment method of steel-copper-graphite semi-solid composite plate, that is, at room temperature, in precision On the rolling mill, the steel-copper-graphite semi-solid composite plate is processed after rolling, and the difference between the copper-graphite coating and the deformation of the steel plate produced by the rolling treatment is used to compensate for the difference between the copper-graphite coating and the shrinkage of the steel plate during the composite solidification and cooling process. The difference, and then reduce the res...
