Predicting the Ultimate Strength of Metals

Caption

The image shows the transformation of a crystalline metal (upper left) to amorphous material (lower right), with an energy difference related to the heat of fusion. The graph in the upper right shows a representative plot of strength vs. crystallite (grain) size and includes the predictions from the model (red line) compared to experimental (x) and simulation (o) data. The graph in the lower left shows the model predictions for grain boundary energies of a variety of metals compared to density functional theory calculations from the literature.
