Description	Decrease of energy costs for annealing to improve the formability of cold forming steel is a hot topic nowadays. The processing time during common soft annealing is approximately in hours. Low-temperature, energy efficient thermomechanical treatment was developed for significant time reduction to a few tens of seconds. It enables a change of morphology from lamellar into the spheroidised form together with refinement of ferritic grains. 54SiCr steel with initial lamellar ferritic-pearlitic structure was used for the experiment. During experimental processing optimization the A c1 temperature was determined for different heating rates. Next, the appropriate heating and deformation temperature was determined as well. The main part of the research was to describe the influence of deformation intensity and holding time between deformations for carbide spheroidisation and recrystallization of ferritic grains. The recrystallized structure which contained ferrite with dispersed spheroidised cementite was achieved by gradual optimization of process parameters. Ferritic grain was refined to 2 ?m and hardness was decreased to a value of about 260 HV10.
