摘　　要：通过对 0 9CuPTiRE耐大气腐蚀钢断口形貌的宏观和微观分析 ,及该钢的冲击性能试验结果 ,探讨了0 9CuPTiRE钢的断裂规律以及冲击韧性与断口形貌之间的关系。结果表明 ,温度对断口形貌的影响较大 ,随着温度逐渐降低 ,试验钢的断口从韧窝型变为解理型 。Associated with the test result of impact pr operties, the fracture m ode of 09CuPTiRE which is a kind of weather-resisting steel was analyzed. The b r eak regulation and characteristic as well as the relation between the impact tou ghness and fracture mode of 09CuPTiRE were studied. The results showed that ther e is the effect of temperature on fracture mode. Along with decrease of temperat ure t he fracture mode is changed from cavitation to cleavage and the impact tou ghness is also reduced.
