Deformation Behavior and Fracture Mechanism of Ni/Al/V Laminated Sheets Studied Through Finite Element Simulation

This study focuses on the integrated forming and reaction preparation of complex thin‐walled components made of Ni–Al alloy, with a special focus on a novel Ni/Al/V laminated sheet prepared by current‐assisted sintering. In this study, high‐temperature tensile tests are conducted, and a layered damage model is constructed based on these experimental results. Finite element analysis is conducted to analyze the deformation behavior and damage evolution of the material. The regions composed of Ni 2 Al 3 and NiAl 3 in the transition layer exhibit brittle fracture, initiating microcracks and propagating from the transition layer, ultimately causing local delamination and overall failure. Furthermore, an asymmetric “W”‐shaped component is fabricated using this material, and damage prediction is successfully achieved through layered damage finite element analysis. This study reveals the deformation and fracture mechanisms of Ni/Al/V laminated sheets under high‐temperature conditions. The findings suggest that future research should focus on optimizing the transition layer to enhance the material's overall performance and explore damage prediction and control methods in more application scenarios.
