TL;DR: In this article, the evolution of precipitation and microstructure during a simulation of the thin slab direct rolling process, in six vanadium based, low carbon, steels with V, V-N, VTi-N and V-Zr additions was studied by optical microscopy, analytical transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDAX) and parallel electron energy loss spectroscopy (PEELS).

TL;DR: In this paper, a study simulating thin slab continuous casting followed by direct charging into an equalisation furnace has been undertaken based on six low carbon vanadium microalloyed steels.

TL;DR: In this paper, a study of four vanadium-based steels which have been processed by a simulated direct charging route with processing parameters typical of thin slab casting, where the cast product has a thickness of 50 to 80 mm (in this study 50 mm) and is fed directly to a furnace to equalise the microstructure prior to rolling.

TL;DR: The change from producing high strength low alloy (HSLA) steel sheet by conventional thick slab casting to producing it by direct charged thin slab casting causes a major change in the evolution of the precipitation.

TL;DR: The fast deflection system described in this paper is suitable for controlling the intensity reaching the detector of a magnetic sector electron spectrometer mounted below an analytical transmission electron microscope and will also be suitable for use with the new and much faster GATAN ENFINA spectromaeter system.
