Nano-steels are a new generation of Advanced High Strength Steels (AHSS), extremely suitable for lightweight automotive applications. The matrix of the steel, which provides ductility and stretch, is significantly strengthened by nanometer-sized precipitates, which can increase the strength level by 30-50%. These steels contain different microalloying additions, such as vanadium (V) and molybdenum (Mo), which form the essential nano-precipitates. A resource-efficient use of these alloying additions requires further knowledge on the formation kinetics of these nanometer-sized vanadiumcarbides (VC). Our aim is to measure the VC-precipitation kinetics in NANO-steel and elucidate the effects of Mo and V additions.
