Abstract Scope |
Faster materials testing methods are needed to quickly determine the ductility of materials. Here we use experiments and modeling to develop a new method to measure the relative ductility in bulk metallic glasses using nanoindentation with high-rate data acquisition. The analysis extracts a single experimental parameter determined from jumps in the load-displacement curves and ranks the compositions accordingly. This method is ideally suited for rapidly scanning libraries of new metallic glass compositions for relative ductility. We show how the method works and that it is remarkably robust to changes in experimental methodology. |
