| Abstract Scope |
Composite metal foams (CMF) are renowned for their lightweight nature, high specific strength, energy absorption capabilities, and thermal properties, making them ideal for nuclear, automotive, aerospace, and defense applications. CMF integrated air-filled hollow metal spheres into a metallic matrix, reducing thermal conductivity and enhancing insulation under extreme environments. This study focuses on the high-temperature mechanical properties of CMF made with steel spheres in a steel matrix. Ex-situ quasi-static compression tests are conducted on CMF samples at room temperature up to 1000°C to understand their temperature-dependent mechanical behavior. In-situ Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy examines microstructural evolutions during the heating process up to 1000°C. A constitutive numerical model predicts CMF's thermomechanical performance, validated by the experimental data. This research aims to enhance understanding of CMF's high-temperature performance and microstructural evolution, advancing their potential applications in extreme heat and loading conditions. |
