Macro hybridized systems consisting of steel encapsulated light metal matrix composites (MMCs) deliver a low cost/light weight composite with enhanced mechanical properties. By exploiting the high strength, modulus, and damage tolerance of steels and high specific stiffness and low density of MMCs while alleviating the high density of steels and the poor ductility of MMCs, a more structurally efficient system can be attained. However, the combination of these dissimilar materials, specifically iron and aluminum, often results in binary and ternary intermetallic compound formation which can exhibit degraded materials properties. X-ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS), and Electron Backscatter Diffraction (EBSD) are utilized to characterize the intermetallic reaction layer formation between the steel and MMCs. This research focuses on evaluating the intermetallic reaction layer formation between aluminum or magnesium MMCs reinforced with Al2O3, SiC, or B4C particles and encapsulated by A36 steel, 304 stainless steel, or Nitronic® 50 stainless steels.
