Grain boundaries, their structure, mechanics and migration, are in the spotlight of this newsletter edition. Better understanding of grain boundaries enables improvement of the mechanical, electronic and chemical behaviour of materials. Here we present the work of three groups which focus on different aspects of this topic.
The significant impact of grain boundaries on the mechanical response of crystalline materials had been recognized ever since the concept of dislocations as carrier of plasticity in metals had been established.
Grain boundaries are important 2-dimensional microstructural elements. They strongly influence most of the properties of polycrystalline materials like mechanical, chemical, or electronic behaviour.
The migration of grain boundaries plays a pivotal role in the evolution of materials’ microstructures, strongly impacting the mechanical, chemical, or electronic response of a material.
