摘要:
采用GB/T 21143—2007规定的钝化线方法测试了X80管线钢延性断裂韧度JIC,并与采用微观断口裂纹伸张区方法确定的表观启裂韧性Ji对比。结果表明:GB/T 21143—2007规定的左边界线判定条件存在数据有效性误判情况,用钝化线方法确定的X80管线钢断裂韧性值偏高,建议在X80管线钢延性断裂韧性测试时保留GB/T 21143—2007中的钝化线形式,左边界线由钝化线偏置量0.1 mm调整为0.03 mm,钝化线偏置量由0.2 mm调整为0.035 mm。
Abstract:
Adopting the blunting line method specified in GB/T 21143—2007 Specification to test the ductile fracture toughness JIC of X80 pipeline steel, and compared with macro fracture crack Ji determined by the micro fracture crack extension zone methods. The results showed that the left border line stipulated in GB/T 21143—2007 misjudged the data, the JIC value of X80 pipeline steel determined by the blunting line method is much higher. It is suggested keep the blunting line form in GB/T 21143—2007 during the ductile fracture toughness test, adjust the left border line offset from 0.1 mm to 0.03 mm, and adjust the blunting line offset 0.2 mm to 0.035 mm.
