Optimization of Low-temperature Thermo-mechanical Treatment on 54SiCr Steel for Spheroidization of Carbides
Original language description
In accordance with the current trends of economic savings efforts are also being made in the field of heat treatments to find new procedures leading to a reduction of manufacturing costs [1-3]. One option is the ASR process (Accelerated Spheroidization and Refinement) [4]. This is a progressive method of thermo- mechanical treatment with incremental deformation at a temperature around Ac1. Application of ASR leads to a spheroidization structure with distributed carbides in significantly shorter times than with conventional heat treatments. The experiment deals with the optimization of the ASR process on 54SiCr steel with ferrite- pearlite initial microstructure including pearlite of lamellar morphology. The influence of strain and cold deformation on breaking the lamellar pearlite structure at a temperature of 700°C was determined. Then the influence of the length of the hold after deformation at temperatures of 680 and 700°C was described. It was found that increasing holding time fro
