摘　　要：为了研究管线钢落锤撕裂试验冲击韧性的影响因素,通过对X65M管线钢在不同温度、不同厚度的条件下进行落锤撕裂试验,并对试验数据进行分析。结果表明,温度和厚度是影响X65M管线钢落锤撕裂试验的重要因素,温度越低,材料的韧性越低;厚度越大,材料的韧性越小。将异常断口作为有效试样参与试验结果评定,结果表明,厚度越大,产生异常断口的的可能性越大。There are many factors affecting the impact toughness of drop weight tear test of pipeline steel.Through the drop weight tear test of X65M pipeline steel at different temperatures and thicknesses,the test data are analyzed.The results show that temperature and thickness are important factors affecting the drop weight tear test of X65M pipeline steel.The lower the temperature is,the lower the toughness of the material is.The greater the thickness is,the smaller the toughness of the material is.The abnormal fracture is used as an effective sample to evaluate the test results.The results show that the greater the thickness is,the greater the possibility of abnormal fracture is.
