The way metals deform or yield instead of breaking depends on the way they yield or deform via plasticity or dislocations since the dislocation likes to get stuck in the impurities as it wanders around as a string in the three-dimensional crystal. The new theories will allow to understand at which stress the material yields at finite temperatures. Last, we look at materials at larger scales with many dislocations. We expect, that what we see on smaller scales with one dislocation will have a similar impact on the strength. The research is based on ideas from theoretical physics and the key scientific questions are studied in realistic metal alloys. The data gathered will allow with Machine Learning to make predictions of these complicated materials. The expected results are a discovery of new physics that helps in understanding, predicting and designing hard metal alloys.
