Abstract

The invention discloses a uniform post-treatment method for a steel titanium bronze 3.5-5 graphite semisolid composite board and belongs to the field of post-treatment research of interface shear strength room temperature rolling of the steel titanium bronze 3.5-5 graphite semisolid composite board. By the uniform post-treatment method, the steel titanium bronze 3.5-5 graphite semisolid compositeboard consisting of a 1.2-millimetre thick 08Al steel plate and a 2.8-millimetre thick titanium bronze 3.5-5 graphite coating layer is subjected to two-pass rolling treatment with a total percentage of reduction of 0.8 percent under room temperature on a precise rolling mill, wherein the pass percentage of reduction of the first pass to the second pass is (1:5)-(1:3), so a shear strength difference value of a transverse interface of the composite board is reduced to within 1.9 MPa.

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 3.5-5 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...
