**About the Editors**

**Andrea Bachmaier** (Dr.) studied Materials Science at the University of Leoben and received her Ph.D. degree in 2011. In 2013, she was awarded an Erwin-Schrodinger scholarship that allowed ¨ her to work on the decomposition process of supersaturated solid solutions and its influence on thermal stability. In 2017, she received the noteworthy ERC Starting Grant. Currently, she is leading the research group "Novel bulk nanomaterials by severe plastic deformation" at the Erich Schmid Institute of Materials Science, Austria. Her research activities focus on the generation of metastable materials, novel nanocomposites and nanocrystalline metal matrix composites by SPD and the investigation of their functional and mechanical properties.

**Thierry Grosdidier** (Prof.) is a metallurgist, working mostly in microstructure–properties relationships, taking into account texture and processing conditions. He received his Ph.D. degree in Material Science from Institut National Polytechnique de Lorraine—Ecole des Mines de Nancy (France) in 1993 and carried on his research career at the University of Surrey (UK) and at the Universite de Technologie Belfort Montebeliard (France). He is now a full time Professor at the ´ University of Lorraine, France. He was Deputy Director of the Scientific Federation Genie Industriel Mecanique Materiaux (5 laboratories, 250 employees) in Metz (France) from 2006 to 2012 and Scientific Expert at the "Advanced Light Metal Innovation Center"—Shanghai Jiao Tong University (China) from 2015 to 2019. He is now co-responsible for the "Impact" department at LEM3 laboratory. Co-author of more than 150 scientific publications, his current topic of interest are (i) powder metallurgy, (ii) surface modifications, (iii) severe plastic deformation and (iv) improvement of H-storage in metal hydrides.

**Yulia Ivanisenko** (Dr.) graduated with a Diploma in Mechanical Engineering at Ufa State Aviation Technical University and received her Ph.D. in applied physics from the Institute for Metals Superplasticity Problems of Russian Academy of Sciences in Ufa, Russia in 1985 and 1997, respectively. She worked as a Research Scientist at the Institute for Nanotechnology, Karlsruhe Institute for Technology since September 2003, where she leads a research group now. Dr. Ivanisenko's research is mostly in the areas of severe plastic deformation, mechanical properties of nanostructured materials and mechanically driven phase transformations.
