Enhancement of-carbide spheroidization in Spring Steel by Low-Temperature Thermo-Mechanical Processing
Original language description
Cold and warm formability of pearlite-ferrite steels can be improved by conventional soft annealing. This processing changes the lamellar morphology of pearlite to a globular one. The advantage of this microstructure is a significant reduction of potential defects which would be initiated at the sharp edges of the carbides as a result of localized stress concentration. Annealed structures possess low yield strength and excellent ductility. This ensures their good cold formability. The problems of thesetechnologies lie not only in long processing times, but also in high energy consumption which makes the final product quite expensive. The time necessary for cementite spheroidization can be shortened by unconventional heat treatment around Ac1 temperature combined with deformation applied at various processing stages. This processing method was utilized for spring steel 54SiCr with ferrite-pearlite original microstructure and lamellar pearlite morphology. The hardness of this structure
