| Abstract Scope |
B4C ceramic reinforced metal matrix composites were produced in layers of varying amount of reinforcement using setup equipped with multi-hopper system. Process optimization was conducted through multiphysics computational process modeling. The effect of the increasing amount of reinforcement was evaluated along the gradation direction using nanoindentation hardness testing and non-destructive effective bulk modulus elastography. The mixing and interfacial characteristics were evaluated using high resolution transmission electron microscopy. A composite with highest fraction of reinforcement on the surface was produced which exhibited a hard surface and a smooth gradation of hardness in the interior regions. |
