In situ composite manufacturing techniques can improve the bond between the matrix and reinforcements in a composite material. This is done by creating the reinforcements within the matrix through the reaction of precursor materials, which form the desired phases. Thermodynamic data and simulation tools can be used to validate the process and design variables, saving time and resources. The aim of this study is to provide a theoretical framework that can be applied to any stage of in situ metal matrix composite development. The framework involves using Gibbs free energy and dissociation criteria of reinforcements to validate the feasibility of the composite system, and assessing composite formation kinetics and microstructural features based on the driving force and diffusion of elements in raw materials. Examples are used to demonstrate how to apply the framework.
