Abstract Scope |
B4C is the lightest ceramic materials with the highest compressive strength. Considerable efforts have been made to enhance the specific strength of the composite by adding higher volume fractions of B4C particles in different metal matrices. It has been realized that the ceramic/metal interface plays a vital role in enhancing the strength of the composite materials. We investigate here using transmission electron microscopy (TEM) microstructure and interfaces of composite materials, such as Al/B4C and Cu/Al2O3, processed in the solid state at relatively high pressure, and correlate with the mechanical properties. We demonstrate that the interface cohesion and mechanical properties have been significantly improved as a result of the formation of metal boride at the interface. This provides a new avenue toward the development of composite materials containing B4C particulates. |
