| Abstract Scope |
Metal matrix syntactic foams (MMSF’s) have been extensively studied due to their remarkable weight reductions and higher specific strengths. MMSF’s are commonly achieved via hollow microspheres that control pore geometry and low melting point metals like magnesium an aluminum. Invar matrix composites with hollow glass microspheres were fabricated and characterized. An electroless nickel coating process was used on the glass microspheres to improve the strength and a means for interfacial bonding with the matrix. 3D X-ray nanotomography was employed to study the microstructure of the new syntactic foam non-destructively at varying volume fractions and nickel thickness. Mechanical characterization was coupled with microstructure data from 3D X-ray nanotomography and SEM imaging to understand the system thoroughly and will be discussed. |
