ADVANCED MATERIALS & PROCESSES | OCTOBER 2023 9 the momentum of the electrons as they move through the material and interact with each other. Instead of all flowing together, the electrons knock each other around in all directions, resulting in electrical resistance. Since the electrons collide more frequently the hotter the material gets, the electrical resistance rises alongside the temperature. According to lead researcher Aavishkar Patel, a better understanding of strange metals could help physicists develop and fine-tune new super-conductors for applications such as quantum computers. simonsfoundation.org, harvard.edu. IMAGING LIGHT ELEMENTS IN GRAIN BOUNDARIES For the first time, scientists at the Max Planck Institute for Iron Research (MPIE), Germany, successfully imaged and analyzed light and heavy elements in the atomic motifs of grain boundaries in steel. Using atom probe tomography and a customized microscopy code, they developed a workflow to analyze and interpret grain boundaries in steels. They identified that certain ordered atomic motifs govern the most important chemical properties of grain boundaries. Engineering those atomic motifs paves the way to more durable, tailor-made materials. “We developed a workflow and code for transmission electron microscopy (TEM) that involves growing bicrystals of an iron-boron- carbon alloy with the same crystal orientation but changing grain boundary planes,” explains lead researcher Xuyang Zhou. “This way, we were able to control the interfering parameters.” The researchers showed that even the mere tilt in the grain boundary plane with identical misorientation impacts the chemical composition and atomic arrangement of the microstructure and makes the material more or less prone to failure. The team is now working with the computational materials design department at MPIE to use the developed code and experimental data for simulating how light elements like boron, carbon, or hydrogen behave in materials. www.mpie.de.
