Abstract Scope |
Here we report the development and results of a computationally-efficient 3-dimensional multiphase Monte Carlo approach for microstructure-scale formation and evolution of “line compound” materials systems such as SiC-Diamond composite materials from carbon and silicon precursors, the selected example. This new model is capable of considering long-range interactions between components or phases as a system evolves, enabling simulation of processes such as diffusion-limited phase transformations concurrently with traditionally-modeled microstructure evolution processes such as grain growth or allotropic phase change. This model has been parameterized for the formation of SiC-Diamond composites using Si and C precursor materials in conjunction with recent experimental efforts, including formation of SiC, as well as growth of graphitic layers at interfaces and thermal behavior during processing. The results are evaluated with phase field model to test the mechanical perfomance of resultant Si-SiC-C microstructures to optimize the precursor configuration and processing conditions. |
