Molecular Dynamics Study of Interdiffusion for Cubic and Hexagonal SiC/Al Interfaces

The mechanical properties of the SiC/Al interface are crucial in estimating overall strength this ceramic-metal composite. present work investigates interdiffusion at using molecular dynamics simulations. One cubic and one hexagonal SiC with a higher probability orientations contact Al examined as two samples metal-matrix nanocomposites whisker particulate reinforcements. These reinforcements Si- C-terminated surfaces interfaces also studied. average main cross-interdiffusion coefficients evaluated single diffusion couple for each system. effect temperature annealing time analysed on self- coefficients. It is found that similar expected, coefficient increases increase. model after can be used to evaluate region future studies.
