The relationship between contact fatigue life and fracture characteristic parameters is studied for two kinds of bearing steel from the measurements of contact fatigue life, fracture toughness KIC and crack

The natural fragments forming process of several explosive-filled Ti-6Al-4V cylinders are studied.The macro-fracture characteristics and the meso-fracture mech-anism of the fragments are also analysed.The results show that the fundamental reasonof the Ti-6Al-4V used as warhead shell material in some of missiles lies in taking advan-tage of the adiabatic shear banding during the shell fracture and the violent oxidation ofthe titanium in high temperature.

atigue fracture lifetimes of Ti_3 Al(NbMoV)alloy under two different heat treatment have been de-termined in cyclic lcad-controlled tests at 700℃ and 1 Hz with a constant maximum stress. It is found that tests at higher mcan stress levels caused creep induced damage,resulting in the inversion of the S-N curves. At corresponding stress amplitude,spocimens solutionized in βsinglephase field exhibited the higher creep-fatigue resistance than that in two-phase field.These macroocopic properties are closely...

atigue fracture lifetimes of Ti_3 Al(NbMoV)alloy under two different heat treatment have been de-termined in cyclic lcad-controlled tests at 700℃ and 1 Hz with a constant maximum stress. It is found that tests at higher mcan stress levels caused creep induced damage,resulting in the inversion of the S-N curves. At corresponding stress amplitude,spocimens solutionized in βsinglephase field exhibited the higher creep-fatigue resistance than that in two-phase field.These macroocopic properties are closely related to steady strain rate and microscopic fracture characteristics.

本文测试了两种热处理状态下的Ti_3Al(NbMov)合金在700℃时保持最大应力恒定、改变最小应力1Hz梯形波加载条件下的疲劳断裂寿命。结果表明,随平均应力增高将导致蠕变损伤加重,致使S-N曲线反向。在相同应力幅时,于β相区固溶的样品比在两相区固溶的样品具有较高的蠕变-疲劳抗力。最后发现,这些宏观性能的变化与稳态应变速率和微观断裂特征是密切相关的。
