(author), Offerman, S.E. (author)In-situ Neutron Diffraction and Small-Angle Neutron Scattering (SANS) are employed for the first time simultaneously in order to reveal the interaction between the austenite to ferrite phase transformation and the precipitation kinetics during isothermal annealing at 650 and at 700 °C in three steels with different vanadium (V) and carbon (C)...journal article 2021

Microstructure, precipitate and property evolution in cold-rolled Ti-V high strength low alloy steelZhang, Xukai (author), Ioannidou, C. (author), ten Brink, Gert H. (author), Navarro Lopez, A. (author), Wormann, Jan (author), Campaniello, Jean (author), Dalgliesh, Robert M. (author), van Well, A.A. (author), Offerman, S.E. (author), Kranendonk, Winfried (author), Kooi, Bart J. (author)A cold-rolled Ti-V high strength low alloy (HSLA) steel was isothermally annealed at 650 °C and 700 °C for different times. A unique combination of techniques including visible light microscopy (VLM), transmission electron microscopy (TEM), matrix dissolution, small angle neutron scattering (SANS) and hardness measurement has been employed to...journal article 2020

(author), Bliznuk, Vitaliy (author), Pappas, C. (author), Sietsma, J. (author), van Well, A.A. (author), Offerman, S.E. (author)The precipitation kinetics of vanadium carbides and its interaction with the austenite-to-ferrite phase transformation is studied in two micro-alloyed steels that differ in vanadium and carbon concentrations by a factor of two, but have the same vanadium-to-carbon atomic ratio of 1:1. Dilatometry is used for heat-treating the specimens and...journal article 2019

Ioannidou, C. (author), Arechabaleta Guenechea, Z. (author), Rijkenberg, Arjan (author), Dalgliesh, Robert M. (author), van Well, A.A. (author), Offerman, S.E. (author)Nanosteels are used in automotive applications to accomplish resource-efficiency while providing high-tech properties. Quantitative data and further understanding on the precipitation kinetics in Nanosteels can contribute to fulfil this goal. Small-Angle Neutron Scattering measurements are performed on a Fe-C-Mn-V steel, previously heat-treated...journal article 2018

Borra, C.R. (author), Vlugt, T.J.H. (author), Yang, Y. (author), Offerman, S.E. (author)Ceria is the main component in glass polishing powders due to its special physico-chemical properties. Glass polishing powder loses its polishing ability gradually during usage due to the accumulation of other compounds on the polishing powder or due to changes in the particle size distribution. The recovery of cerium from the glass polishing...journal article 2018
