| 摘 要： | 对１６Ｍｎ钢ＣｈａｒｐｙＶ型缺口（ＣＶＮ）试样进行了系列温度的示波冲击试验。揭示出断裂载荷随温度的变化呈现反“Ｓ”形特性，且在断裂载荷谷值点对应的温度ＴＶＣ处发生断裂的韧脆转变行为。研究表明温度ＴＶＣ受控于材料的解理特征应力ＳＣＯ。

| Abstract: | Instrumented impact test of standard Charpy V notched specimens of 16Mn steel were conducted at series temperatures.The fracture load vs.temperature curves are reversed "S" shape.It is found that the temperature T V C corresponding to the valley value of fracture load represents the ductile/brittle transition of the CVN specimen and is controlled by the cleavage characteristic stress S CO . |

| Keywords: | notched specimen instrumented impact ductile/brittle transition |
