管线钢落锤撕裂试验与摆锤冲击试验

Drop hammer tear test and pendulum impact test of pipeline steel

管线钢落锤撕裂试验与夏比摆锤冲击试验的测试性能是材料的两个重要参数,有助于确定材料或产品的安全性和可靠性。采用两种不同规格、不同性能的管线钢在不同温度进行落锤撕裂试验和夏比摆锤冲击试验。对这两种试验方法的摆锤冲击剪切断面率和落锤剪切面积分数进行对比,研究两种试验结果即摆锤冲击剪切断面率和落锤剪切面积分数的差异及其相互关系。结果表明,两种管线钢在不同温度的落锤撕裂试验和摆锤冲击试验下,摆锤冲击剪切断面率和落锤剪切面积分数的变化规律基本一致。

The performance of drop hammer tear test and pendulum impact test of pipeline steel are two important parameters of materials,which can help determine the safety and reliability of materials or products.Two pipeline steel samples with different specifications and different properties were used to perform drop hammer tear test and Shaabi pendulum impact test at different temperatures.The impact shear section rate and the drop hammer shear area fraction in two test methods were compared.The difference and relationship were studied based on the test results.The results showed that the change laws of impact shear section rate and the drop hammer shear area fraction were basically consistent during the temperature variation for two pipeline steel samples with different specifications and different properties in drop hammer tear test and pendulum impact test.
