The Charpy impact properties of high strength pipeline steel with different microstructure were investigated.

研究了具有不同微观组织类型的高强度管线钢的夏比冲击韧性。

According to empirical equation between the Charpy impact energy and fracture toughness to estimate is common method.

常用的做法是根据管材的冲击韧性与断裂韧性之间的关系式进行估算。

The amount of energy required to fracture the material by a single blow is measured by means of a Charpy impact test.

单次冲击破坏材料所需的能量通过却贝摆锤冲击测试的方法测得。

The following table lists the minimum design temperatures for each pipe size, above which charpy tests are not required.

下表列出了每个管道的最小设计温度，超过它的冲击测试不需要。

The predicted Charpy impact energy from measured and predicted strength, was in good agreements with the measured values.

并分别采用实测与预测的强度值对夏比冲击吸收功进行了预报，预报结果和实测值吻合较好。
