One of the strongest engineering materials is pearlite, a material which gains its strength through severe plastic deformation. At the same time the exact mechanisms behind this strength are still not known, thus the design of ultrahigh strength materials is retarded. This newsletter edition provides latest insights on experimental and theoretical approaches to unravel the strengthening mechanisms. Furthermore, we are welcoming two new group leaders, Dr. Baptiste Gault from Oxford University and Prof. Jochen Schneider from RWTH Aachen, who have recently been appointed heads of the groups “Atom Probe Tomography” and “Self-Reporting Materials”, respectively. Both colleagues are briefly introduced in the section “Scientists at the MPIE”.
