Processing and properties of SiC-particulate reinforced titanium matrix composites by shock wave consolidation


Using shock wave consolidation, fully dense SiC-particulate reinforced Ti matrix composite compacts that are free from interfacial reactions and macroscopic cracks have been obtained. Proper post-consolidation annealing has been explored to improve impurity segregation and, thus, the ductility of the matrix. Various heat treatments of the composites produce controlled interfacial reaction zone sizes. Results of mechanical testing indicated that good ductility is retained in the Ti-SiC composites with a minimum interfacial reaction layer (<0.1 µm), while no interface reaction or an interfacial reaction layer of 0.25 µm thick or more is detrimental to the tensile ductility and strength of the composites.
