Even aftertreatment method for steel titanium bronze 3.5-3.5 boron nitride semisolid composite boards

Abstract

The invention discloses an even aftertreatment method for steel titanium bronze 3.5-3.5 boron nitride semisolid composite boards, belonging to the research field of interface shear strength room temperature rolling aftertreatment for the steel titanium bronze 3.5-3.5 boron nitride semisolid composite boards. In the method, two-pass rolling treatment is carried out on the steel titanium bronze 3.5-3.5 boron nitride semisolid composite board prepared from 08Al steel plates with the thickness of 1.2mm and a titanium bronze 3.5-3.5 boron nitride coating with the thickness of 3.0mm at the room temperature on a precise rolling mill, wherein the total down rate is 0.7%, and the pass down rate proportion of a first pass to a second pass is 1:4.5-1:2, thus the different value of the lateral interface shear strength of the composite board can be reduced within 2.1 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 3.5-3.5 boron nitride semi-solid composite plate. 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 additio...
