A first-ever complete map for elastic strain engineering

The “map,” or the phonon stability boundary, is a graphical representation that plots the stability regions of a crystal as a function of strain. This map helps scientists and engineers determine the conditions under which a material can exist in a particular phase and when it might fail or transition to another phase. By analyzing the phonon stability boundary, researchers can understand material properties at extreme conditions and design new materials with desired characteristics. Credit: Zhe Shi et al

Without a map, it can be just about impossible to know not just where you are, but where you’re going, and …
