This study is concerned with the analysis of fracture toughness in the transition temperature region of APIX70 pipeline steels according to ASTM E1921 standard test method. Two kinds of steels were fabricated by varying finish rolling temperatures, and their microstructures and mechanical properties were examined. Elastic-plastic cleavage fracture toughness, K-Jc. was determined by three-point bend tests of precracked Charpy V-notch specimens, and then the measured K-Jc. values were interpreted by the three-parameter Weibull distribution. Fractographic observation indicated that the critical distance from a precrack tip to a cleavage initiation site linearly increased with increasing critical J value. Effects of martensite-austenite constit...
