Abstract

Comparative analysis of the results of physical and computer modeling of pressure welding of coarse-grained HN58MBYUD heat-resistant nickel alloy using ultrafine-grained gasket is presented. According to the results of numerical simulation of the stress strain state, maximal values of strain are observed in the periphery of the solid phase bonding (SPB) zone. In this zone, ultrafine-grained interlayer undergoes low-temperature (850°C) localized superplastic deformation, which promotes the formation of a high-quality SPB. The effect of the gasket thickness on the uniformity of stress and strain distributions in the SPB zone is analyzed.
