**Preface to "Crystal Plasticity (Volume II)"**

Dear Colleagues,

The extensive response to our call for papers for the first Special Issue volume on "Crystal Plasticity" was very staggering. I am sure that it was also a surprising feat for 25 excellent articles to be published in such a short amount of time.

The articles are freely accessible to read through the following link: https://www.mdpi.com/ journal/crystals/special issues/Crystal Plasticity.

Our previous efforts have provided us with a completely new collection of original state-of-the-art research papers on both theoretical and experimental aspects of plastic deformation. Indeed, the wide spectrum of submitted papers allowed us to merge the most important research areas of the crystal plasticity field, i.e., research on the theoretical modeling of dislocation mechanisms and lab-scale validation of materials' structural/mechanical responses to (semi-)industrial processing. Furthermore, both conventional (e.g., steels, nonferrous alloys) and novel (intermetallics, composites, high entropy alloys) materials were investigated. It was my honor to host well-recognized worldwide authorities as well as young researchers and post-docs taking the "next step" in their scientific careers. This versatility of contributing authors and topics provides more proof for the high interest of the scientific community in revealing materials' behaviors at the atomic scale to macroscale under external loadings.

After closing the first volume of Special Issue, we had the feeling that there was still much research to be conducted in the field of crystal plasticity, and thus much potential for publishing activities. . . Therefore, we had no doubts about announcing the second volume of a Special Issue on crystal plasticity. In this book, a collection of completely new 26 original works is presented for readers.

We hope that the second volume of our Special Issue will be interesting for the scientific and academic communities, and that it will bring much inspiration for future research activities in the field of crystal plasticity.
