Predicting tensile and compressive mechanical properties of bimodal nano-aluminum alloys

We present a new analytical model for predicting the tensile and compressive mechanical properties of bimodal nano-aluminum alloys. The model relies on simple material variables that show a Hall-Petch-like grain size dependence including a newly defined ductility parameter which can be used with the Hollomon equation to allow for the prediction of failure stress and strain. When the model is applied to bimodal nano-aluminum alloys, the results show excellent agreement with the experimental observations.
