摘要

摘要:用仪器冲击试验的方法研究了一种低碳钢和一种瑞典铁在- 196 ~ 150℃温度范围内的力学性能。载荷与温度曲线与缺口弯曲试验曲线表现出相似的特征。研究了试样的几何形状和显微组织对断裂应力的影响，并根据滑移引发解理断裂的临界拉应力对结果进行了讨论。

Instrumented Impact Testing of Low-Carbon Steels

AbstractThe mechanical properties of a low-carbon steel and a Swedish iron have been examined over a range of temperatures from − 196 to 150°C by means of an instrumented impact test. Load vs. temperature curves exhibit similar features to curves obtained from notch bend tests. The effects of specimen geometry and microstructure on the fracture stress have been studied and the results are discussed in terms of a critical tensile stress for slip-initiated cleavage fracture.
