The article of Assistant Professor Dr.-Ing. S. Papaefthymiou et al. entitled “The Effect of Heating Rate on the Microstructure of a Soft-Annealed Medium Carbon Steel” was chosen by the editors of Steel Research International for the cover page of the 90 years celebration of the journal in the October issue.
The cover images represents the normal direction inverse pole figure of a steel with 0.12%C; 2%Mn; 1.26%Si, 90% cold rolled and heated to 760°C with 3000°C/s and subsequently water quenched. The IPF maps show of martensite (small darker islands ) in partially recovered but not recrystallized matrix. White lines show low angel grain boundaries (5-15° misorientation) forming polygons (dislocation cells) during recovery. Black lines are high angle grain boundaries with misorientation 15-65°. Further details can be found in the article by Spyros Papaefthymiou and co-workers, article number 1700158.
