In the paper, it is found out that the defects at bottom of notch of impact specimen caused by improper processing lead to the test force forms stress concentration again at bottom of notch of specimen in the impact test through analyzing the reasons for the abnormal test results of impact property for J55 casing pipe of Baotou Steel. The normal stress at the notch of impact specimen exceeds the cohesion strength of material before the specimen deforms so that the specimen is easy to tend to brittle rupture and the impact energy of material is decreased in the actual detection.

文章通过对包钢J55钢级套管冲击性能检测结果异常的原因分析,发现因不当加工所造成的冲击试样缺口底部缺陷的存在,导致在冲击试验过程中,试验力在试样缺口底部缺陷处再次形成应力集中。冲击试样缺口处的正应力在试样发生变形之前超过了材料的内聚强度,从而导致试样更易于趋向脆性断裂,造成材料在实际检测中冲击功的减小。

文章通过对包钢J55钢级套管冲击性能检测结果异常的原因分析,发现因不当加工所造成的冲击试样缺口底部缺陷的存在,导致在冲击试验过程中,试验力在试样缺口底部缺陷处再次形成应力集中。冲击试样缺口处的正应力在试样发生变形之前超过了材料的内聚强度,从而导致试样更易于趋向脆性断裂,造成材料在实际检测中冲击功的减小。

In the paper, it is found out that the defects at bottom of notch of impact specimen caused by improper processing lead to the test force forms stress concentration again at bottom of notch of specimen in the impact test through analyzing the reasons for the abnormal test results of impact property for J55 casing pipe of Baotou Steel. The normal stress at the notch of impact specimen exceeds the cohesion strength of material before the specimen deforms so that the specimen is easy to tend to brittle rupture and the impact energy of material is decreased in the actual detection.
