摘要

This article mainly investigates the microstructural characteristics of the interface in the Incoloy825/P110 bimetallic composite material. By combining molecular dynamics calculations with microstructure simulations, an MS (Materials Studio) unit cell model was established to compute the mechanical parameters of the material, such as the Lamé coefficients, Elastic modulus, and Poisson's ratio. Furthermore, the study analyzed the small-range fluctuations of composite interface atoms within a temperature range of 1420 ± 25 K, the stable fluctuation range of dynamic energy changes, and the stress-strain curves. Meanwhile, through microscopic experiments, the morphology of austenite and martensite structures in the bimetallic composite material was investigated, revealing the diffusion behavior of Ni, Fe, and Cr elements at the bimetallic composite interface. The thickness of the composite layer was approximately 12.2 \(\mu m\) μ m , and the Vickers hardness was measured to be 312.3 HV. The research shows that the bimetallic composite material and its interface exhibit excellent mechanical properties, providing theoretical guidance and technical support for the further optimized design of bimetallic composite seamless tubes.
