Abstract

The invention discloses a superplastic rolling method based on high-intensity laser scanning dissimilar metal composite materials, which is completed by the following steps: S1) putting together dissimilar metal materials with different melting points in a horizontal V-shape; S2) surface-processing the metal materials Surface treatment with organic solvent after grinding treatment; S3) signal receiving from the sensor, the laser device is ready to heat the surface of the dissimilar metal material in a transverse V shape, so that the inner surface is first melted; S4) laser heating; S5) using a roller Rolling is carried out, and the two dissimilar metal materials reach the front of the roll under the action of the conveyor belt, and the two dissimilar metal materials are combined under the rolling of the upper and lower rolls, and the overall composite metal is in a high-temperature superplastic state. The main beneficial effect of the present invention is that the laser quickly scans the inside of the dissimilar metal material and heats the external rolling, so that the delamination phenomenon of the dissimilar metal material is reduced and the whole reaches a superplastic state, forming a composite material with a superplastic state.

Description

Technical field: [0001] The invention relates to the technical field of superplastic rolling of dissimilar metal composite materials. More specifically, it relates to a method of superplastic rolling of laser-heated dissimilar metal composites. Background technique: [0002] The superplasticity of dissimilar metal composites is a property of large elongation and small stress, which is easy to form. It is widely used in aerospace, automobile, and carriage manufacturing. Superplasticity refers to the property that a material exhibits a high elongation rate of a metal material under certain internal and external conditions. In the present invention, the internal condition is a laser heating process, and laser heating makes the combination of dissimilar metals more tightly, reducing the amount of dissimilar metals. hindrance at the interface between metals. The external condition is the rolling force of the rolling mill. Under the action of a large rolling force, the distance ...
