Web21 dec. 2016 · The annealing experiments were conducted using an electrical resistance furnace. The holding time of annealing was set at 1.5 to 2.5 min/mm according to the thickness of steel sample. Three holding times were applied for each test temperature. The austenitizing time and spheroidizing time were designated as t 1 and t 2, respectively. Webeliminate the effect of annealing time on the microstructure and to focus entirely on the effect of heating rate. The last stage was to cool down the material to room temperature at ~160 ºC/s. The peak temperature of 860 ºC for intercritical annealing was selected based on the outcomes of the dilatometry measurements (see Section 3.1). life avis
