In a new study published in the journal Nature Communications, researchers have identified a method for stabilizing the growth of precipitates at grain boundaries. By using a combination of high-resolution atom probe tomography and in situ transmission electron microscopy, the team was able to explore the dynamics of precipitate growth at the grain boundary. They discovered that the presence of an alloying element such as magnesium can prevent the precipitation process from occurring, thus stabilizing the grain boundary. This could have a significant impact on the development of more efficient materials for use in a number of applications, including aerospace and automotive engineering.
