| Abstract Scope |
Al2O3 and B4C have considerably high compressive strength and considerable efforts have been made to manufacture metal matrix composites (MMCs) to enhance the mechanical properties by adding various volume fractions of B4C or Al2O3 powder to achieve higher homogeneity of ceramic particles in the matrix. Here we present the recent development of MMCs with B4C processed in the solid state. In all cases, the composites show higher hardness as compared to the base metals and alloys. We present the microstructure and interfacial characteristics of the composites using x-ray diffraction (XRD) and transmission electron microscopy (TEM), and demonstrate that the formation of interfacial phase during sintering improves interface cohesion and mechanical properties significantly. |
