Abstract

A stainless steel-based composite reinforced with TiN particles has been developed for potential applications in industry. The results show that the compatibility between the matrix and reinforcement is good and the bonding between the two phases is strong and of the diffusion type. The ductility and toughness of the composites are lower than those of the matrix. The strengthening behavior of the composites, however, is not straightforward. It is also found that reinforcements that differ only in particle-size distribution can bring about a large change in the mechanical properties of the composites. It is believed that the microstructural change of the matrix after incorporating the reinforcement, together with the load-bearing effect of the reinforcement, gives rise to the results.
