New process for accelerated carbide spheroidisation of RSt 37-2 steel

Popis výsledku v původním jazyce

Conventional soft annealing of steel is normally carried out in continuous and batch furnaces with annealing times of up to several tens of hours. The typical annealing temperature is just below the transformation temperature AC1, but the soaking times are varied. The hold is followed by slow cooling to room temperature. During annealing, recovery of the crystalline lattice takes place in the ferrite matrix. Carbide spheroidisation occurs as well, i.e. the cementite lamellae transform into globular cementite. As a result, strength and hardness decrease, ductility increases and the ability of the steel workpiece to undergo plastic deformation is recovered. Normally, toughness and other dynamic response parameters increase significantly. The annealing process can be accelerated by temperature cycling around the transformation temperature AC1. However, according to literature sources, this process takes many hours as well. Annealing above AC1 and subsequent cooling is also possible. This
