Abstract

Currently, thin bimetallic strips consisting of difficult-to-form alloys are in demand products in modern high-tech industries. That is why the issue of the production of such strips is relevant and should be considered from a technological point of view. Based on this, this article is devoted to an experimental study of the process of asymmetric cold rolling of bimetallic strips obtained by explosion welding and consisting of an aluminum layer of D16 grade and a titanium layer of VT-1-0 grade. The central objective of the study is to obtain a bimetallic strip made of mentioned materials with a thickness of 0.3 mm by introducing kinematic asymmetry into the rolling process, expressed in a mismatch of the circumferential rotational speeds of the working rolls. In turn, the scientific novelty of the work lies in the study of the factors influencing the deformation of such strips. The results of the study revealed deformation features during rolling of the aluminum-titanium composite obtained by explosion welding. In particular, these features include: layer-by-layer deformations, strip curvature, and capture conditions during asymmetric rolling with individual roller drive and with one drive roller. Further consideration of this issue, as well as solving the optimization problem, will make it possible in the future to first form an experimental technology for producing such strips, and then improve it to production.
