Abstract

The hereby work presents the influence of an additional annealing prior to heat treatment on the final properties of investigated steel. Often companies despite softened conditions of ordered materials are performing further annealing. In many cases it is just a waste of energy and money because there is already an adequate condition to perform heat treatment. In present study two widely used 100Cr6 and 145CrV6 steels were selected. Two sets of samples were prepared first in the delivered state and second after additional annealing carried out in the laboratory furnace. For each steels a typical heat treatment simulation was performed on the Linseis L78 R.I.T.A. (Rapid Intensive Thermal Analysis) dilatometer. Critical temperatures and thermal expansion coefficient were determined and compared. The microstructures for each set of samples before and after heat treatment were compared. Obtained results determined the suitability of the additional soft annealing process.

Keywords: steel, dilatometric investigations, annealing, heat treatment, thermal expansion coefficient
