Abstract

The functionally gradient material (FGM), consisting of pure Al outer layer and Al–B4C inner layer, was fabricated by semi-continuous casting with subsequent hot rolling. B4C particles of four different sizes (11, 26, 53, and 75 μm) were used as the reinforcement phase. The effect of B4C size on the microstructure and mechanical properties of the FGM composites was analyzed. Obtained results show that the B4C particles are uniformly distributed in the inner layer. With the increase of B4C particle size, the Brinell hardness of these FGMs increases, but the impact properties decrease.
