“…This layering defect could be produced during the packing process or during the infiltration process. Similar layering defects have been observed for coarse particles by Garcia-Cordovilla et al [9], Alonso et al [10], and by Long and Beffort [11].…”

“…The most commonly used methods for manufacturing of metal matrix composites (MMC's) are casting techniques [1][2][3] and powder metallurgy (P/M) techniques [4][5][6]. P/M processing proved to be effective in avoiding the limitations and defects of casting techniques and in producing materials with superior properties inherited from the powder characteristics usually related to rapid solidification.…”

“…The above argument should also hold, at least partially, for reasoning the contribution of the reinforcing particles to the increase of the elastic constant in discontinuous reinforcement MMCs, since the loadtransfer process is also involved in the elastic range [29,30].…”

In the present study, attempts were made to coat the B4C powders with TiB2 via a sol-gel process, and then squeeze cast A356 matrix composites reinforced with coated B4C particles were fabricated. X-ray diffraction studies also confirmed the existence of boron carbide and some other reaction products such as TiB2, AlB2 and Al3BC in composite samples. It was observed that the amount of porosity increased with increasing the volume fraction of composites. Tensile behavior and hardness of unreinforced alloy and composites were evaluated. It was noted that the elastic constant, strain-hardening and UTS of the metal matrix composites (MMCs) were higher than those of the un-reinforced Al alloy and increased with increasing of coated B4C content. The strengthening of particulate reinforced metal-matrix composites is associated with a high dislocation density in the matrix due to the difference in coefficient of thermal expansion between the reinforcement and the matrix.
