Abstract

Abstract

In order to study the low cycle fatigue (LCF) properties of Zr-Sn-Nb alloy welded sheets, microstructure simulation and finite element method were combined based on the LCF test method of Zr-Sn-Nb alloy sheets in this study. The microstructure, microhardness and uniaxial tensile properties were compared and evaluated, and it turned out that it was basically feasible to simplify the complex microstructure of welded joint funnel sample by microstructure simulation. Finally, the stress-strain transformation of welded sheet funnel sample was established based on coupling, and the LCF properties of welded sheets were evaluated by this method. The results show that the LCF test method established in this study for Zr-Sn-Nb alloy welded sheets can be used to evaluate the LCF properties of the welded sheets.
