M2i PhD researcher Chrysoula Ioannidou received international Vanadium Award from Materials, Minerals and Mining (IOM3) institute for the most outstanding paper in the metallurgy and technology of vanadium and its alloys.

Chrysoula has worked on TTW funded project “NANO-STEEL: Resource efficient Nano-Steels through in-situ and simultaneous studies of the precipitation and phase transformation kinetics” under supervision of Erik Offerman and Ad van Well from TU Delft and co-funded by Tata Steel (project # 14307/ S41.5.14548).

The development of new and more resource-efficient nano-steels (ferritic steels with nano-sized precipitates) for high-tech automotive applications that require high strength, tensile elongation, high stretch-flangeability and bendability, is expected to contribute to the partial replacement of the conventional hot-rolled AHSS used in the most demanding automotive chassis and suspension systems. Vanadium carbide precipitates are well known for precipitation strengthening in steels. The results obtained in NANO-STEEL project provide quantitative information focused on the kinetics of the vanadium carbides in steels, on its interaction with austenite-to-ferrite phase transformation and on the evolution of the precipitate chemical composition during annealing at 650 °C or at 700 °C. The acquired quantitative results contribute to modelling the precipitation kinetics in vanadium micro-alloyed steels, which leads to improved steel design and performance for automotive applications.

M2i would like to congratulate Chrysoula, Ad, Erik and co-authors with this achievement.
