Development of Bonding Mechanisms for Different Materials During Forming

Abstract

In developing technology for producing bimetal and layered composite materials, considerable attention is devoted to bonding of layers and provision of a strong joint. Several bonding mechanisms are known, although the majority of them are qualitative in nature and do not make it possible to calculate compound formation with combined deformation of different metals. A bonding mechanism and criteria are proposed on the basis of mechanical features of metal forming. The mechanism and design procedure developed make it possible to evaluate the effect of processing factors on layer joint strength in steel-aluminum bimetal and to model its manufacturing technology.
