| 英文摘要 | The fracture toughness of SA508-III steel was studied in the temperature range from room temperature to 320A degrees C using the J-integral method. The fracture behavior of the steel was also investigated. It was found that the conditional fracture toughness (J (Q)) of the steel first decreased and then increased with increasing test temperature. The maximum and minimum values of J (Q) were 517.4 kJ/m(2) at 25A degrees C and 304.5 kJ/m(2) at 180A degrees C, respectively. Dynamic strain aging (DSA) was also observed to occur when the temperature exceeded 260A degrees C with a certain strain rate. Both the dislocation density and the number of small dislocation cells effectively increased because of the occurrence of DSA; as a consequence, crack propagation was more strongly inhibited in the steel. Simultaneously, an increasing number of fine carbides precipitated under high stress at temperatures greater than 260A degrees C. Thus, the deformation resistance of the steel was improved and the J (Q) was enhanced. |
