Abstract
A statistical analysis has been made of the number and length of particle-particle (P-P), particle-matrix (P-M) and matrix matrix (M-M) interfaces present in solid state and liquid phase diffusion bonded joints in a particulate metal matrix composite (17 vol % SiC/Al-Li 8090 alloy). All solid state bonds had planar bond interfaces with the polished particle facets aligned in and parallel to the bond interface. The particle interface lengths in 400 μm long sample lengths in the L direction in a bond interface could vary from zero to over 50% of the sample length, with typical values for a random sample of 8% and 22% for P-P and P-M interfaces, respectively.
Liquid phase diffusion bonded joints contained a higher volume fraction of particles in the bond region, but the bond interface was non-planar and particle interfaces were not aligned.
The significance of these results for the strength and processing of diffusion bonded composites is discussed.
