Finite element modeling of high-strain-rate systems such as the cold spray process has become more common with the significant increase in high performance computing. Advances in high-strain-rate material models beyond the basic Johnson-Cook constitutive model have improved finite element predictions and the ability to model the physics of the bonding process. Finite element analysis has been helpful in understanding the particle impact event and has laid the foundation for the development of spray parameters for certain material systems. Historically, cold spray impact models were not advanced enough to investigate changes in microstructure and secondary phase content due to their complexity and a limit in computing resources. A finite element model has been developed using multiple software tools and advanced characterization methods to investigate the effect of secondary phases and grain sizes on a single cold spray particle impact. The effect of secondary phases are investigated and compared against experimental results.
