Technologies for the Manufacturing of Multi-Layered Hollow Structures by Superplastic Forming

Hollow multilayered structures are increasingly used in various fields of engineering and technology. One of the most important applications is шт aircraft engine construction and power-plant engineering. In recent years, the methods of superplastic forming have started to be used to obtain hollow parts specified for different areas. However, despite significant advances in this field, these technologies have several drawbacks, leading to the emergence of technological defects, particularly those associated with the the effect of Baushinger. In this regard, this article discusses the development and study of a technology for production of multilayer hollow constructions by superplastic forming, in particular, degradation process of adhesive bonds in areas, forming cavities in a constructional workpiece. It is shown that the use of more delicate effects to create the breaking away of the load enables the reduction of process defects in the part.
