A through Process Model for Cold Sprayed Aluminum Alloys

A Through Process Model (TPM) has been developed to relate the process parameters to the microchemistry, microstructure and mechanical properties of cold sprayed aluminum alloys. The model is divided in the four basic steps in the process; powder production, powder preparation, cold spraying and post processing. The development of the powder’s microstructure during atomization and power preparation for 6061 and 5083 powders will be discussed in terms of computational thermodynamic and kinetic model predictions of the phase development will be presented. These predictions will be compared with experimental results. In this paper an overview of the model will be presented and discussed. Some model predictions and experimental verification will also be included.
