Frst exact model for diffusion in magnesium alloys

In order to develop new materials, material engineers need to be able to predict how fast impurity atoms diffuse, or spread, in a crystal over a range of temperatures. Using new computational techniques, researchers have constructed the first exact model for diffusion in magnesium alloys. While magnesium is the lightest structural metal, this new model could mean big things for material engineers, as it can also be used to predict how atoms diffuse in many other materials.
