Fracture toughness determination of P91 steel according to ASTM E1820 and ISO 12135

Popis výsledku v původním jazyce

Purpose: This paper attempts to discuss the problems associated with the determination of fracture toughness values for P91 steels according to the tests standards ASTM E1820 and ISO 12135. Design/methodology/approach: The most applied standards for fracture toughness values determination in the ductile region are ASTM E1820 and ISO 12135. Both standards are intended to determine fracture toughness values in the ductile region. However, there are remarkable differences which leads to different values ofobtained fracture toughness parameters such as JIC or CTOD. Findings: Within this work the P91 steel was characterized by fracture mechanics and fracture toughness parameters according to the test standards ASTM E1820 and ISO 12135 were determined. It was shown that despite of the fact that both test standards are designed to provide engineering fracture toughness for ductile crack initiation the evaluated fracture toughness values differ strongly depending to the applied standard.
