Dillatometric Study of 100CrMnSi6-4 Bearing Steel Hardening from Different Quenching Temperatures
Original language description
Accelerated carbide spheroidisation enables significant shortening of time necessary for formation of steel microstructure consisting of ferritic matrix and globular carbides. Research of accelerated spheroidisation showed that it is possible to spheroidise lamellar pearlite within several minutes. Carbide particles and the grain size of the matrix are significantly smaller after accelerated carbide spheroidisation process in comparison with conventional soft annealing. This fact ensures finer structure after hardening and this shows that the microstructure and properties of final hardened product are dependent on previous annealing. Finer carbides in structure enhance hardness and facilitates carbide dissolution during austenitization. This effect enables quenching temperature lowering and it reduces the energy demand of the quenching process and mitigates the risk of residual stresses and distortion. Steel 100CrMnSi6-4 microstructure, properties and Ms temperature are compared in view of various kinds of spheroidisation and quenching temperature by dilatometric measurement.
