| Abstract Scope |
Steel Composite metal foam (CMF) is a light-weight material composed of steel hollow spheres embedded in a steel matrix manufactured via powder-metallurgy technique offering higher heat resistance and strength-to-density ratio than solid steel making it suitable for potential application in extreme environments. This work focuses on investigating the performance of steel CMF in various extreme environments of heat, fire and impact via both experimental and modeling approaches. Advanced experimental techniques such as in-situ heating and loading, in-situ scanning electron microscopy, solid state joining as well as multi-phase numerical modeling and COMSOL multi-physics modeling will be discussed. The numerical results are validated against experimental findings to compute the minimum critical specifications of steel-CMF for protection against various environments. It demonstrates how the air-filled hollow steel spheres impede the flow of heat and mitigate impact/ loads all at a lower weight than solid steel while providing the benefits of steel. |
