The investigation of the origin and formation of material microstructures during processing and the effect that microstructure has on the properties of materials are questions of central importance in materials science and engineering. This topic covers symposia for presenting and discussing recent developments in this field, which focus on advancements of characterization techniques and its application in the macro, micro, nano as well as atomic scale of all kinds of materials. Advances in characterization nowadays often mean the explicit consideration of the 3D nature of microstructures. In addition to this, in-situ characterization and in operando techniques are becoming increasingly important. And finally, high throughput characterization is growing more and more powerful. Often successful symposia in this field have an interdisciplinary character and are very welcome.
