Optimization of Low-temperature Thermo-mechanical Treatment on 54SiCr Steel for Spheroidization of Carbides

Popis výsledku v původním jazyce

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
