Microstructure and Properties of Hardened 100CrMnSi6-4 Bearing Steel after Accelerated Carbide Spheroidisation and Long-duration Annealing
Original language description
The experimental programme of accelerated carbide spheroidization deals with significant shortening of the time necessary for producing a steel microstructure consisting of ferritic matrix and globular carbides. The conventional way to obtain such structure is long-duration soft annealing after hot forming of the semi-product. Research of accelerated carbide spheroidization showed that it is possible to spheroidise lamellar pearlite by thermomechanical or thermal treatment within several minutes. The thermomechanical treatment consists of forming at temperatures around the Ac1 temperature, whereas the thermal treatment is based on temperature cycling around the Ac1 temperature. From the morphological point of view, accelerated carbide spheroidization produces microstructures very similar to those resulting from conventional soft annealing, but the carbide particles and the grain size of the matrix are significantly smaller. Finer microstructure results in higher hardness than in conven
