摘要
抵抗裂纹扩展能力是管线钢的重要性能之一。对三种管线钢进行了电子测力冲击试验,分析和比较了冲击载荷-变形曲线和各项指标,根据曲线判断了不同级别管线钢的抗裂纹扩展能力。
The ability of resisting crack expand is the main properties of pipeline steel, This paper studies and compares impact curve of three kinds of pipeline steel by impact test. The test results shows that impact curve reflects the ability of resisting crack expand of materials studied.
