Influence of Two Different Finishing Rolling Conditions on Fracture Toughness of Steel Plate

Popis výsledku v původním jazyce

One steel plate (19 mm in thickness) was rolled under two various conditions. For two manufactured final materials marked as A and AF fracture toughness parameters under intermediate conditions of loading rate were determined. Material A was conventionally rolled under working conditions with the finishing rolling temperature on the level of 698°C with subsequent cooling on the air. Ferrite-pearlite matrix with discontinuous fine pearlite bands formed the final microstructure. The second material AF wasmade from material A and its consequent laboratory simulation of thermo-mechanical control process (TMCP) including accelerated controlled cooling (ACC) at the rate of 19°C.s-1 between the temperatures of 810°C and 500°C to eliminated the harmful banding. The difference in transition temperature of both materials was 31°C. Notch toughness results served for mathematical calculation of fracture toughness values.
