X70管线钢断裂韧度的测试分析
FRACTURE TOUGHNESS TESTING OF X-70 PIPELINE STEEL
【摘要】 采用阻力曲线法测定了X70管线钢的断裂韧度。结果表明,X70管线钢的相对屈服强度较低,而韧性极高,抗撕裂能力很好;JR阻力曲线法不适用于X70管线钢;采用不同标准对试验数据进行处理,结果相差较大。
【Abstract】 Fracture toughness of X70 pipeline steel was tested with the method of resistance curve of energy value J. The results showed the method of energy value J was unsuitable to X70 pipeline steel, due to the lower relative yield strength,high toughness and better ability to resist cracking. The results were different with different standards to deal with the data.
