In addition, the influences of loading rate, fatigue precracking stress intensity level, and fracture morphology of fatigue precracked zone on K Iscc were discussed. fractures (materials) stress corrosion crack propagation rising load K Iscc testing threshold stress intensity factor...

...R Padmanabhan; N Suriyayothin; WE Wood Stress corrosion cracking of 300-M steel (Unified Numbering System [UNS] K4420) was monitored using an acoustic emission transducer. Stress corrosion cracking properties were altered through heat treatments and the relationships between the resulting...

...JA Joyce; DF Hasson; CR Crowe The objective of this work was to develop and demonstrate a computer data acquisition system to monitor the stress corrosion cracking of laboratory cantilever specimens. Present methods using optical techniques require long time periods to establish the crack growth...

...RC Dorward; KR Hasse; WJ Helfrich Stress corrosion tests on precracked double-cantilever beam specimens from 2000- and 7000-series aluminum alloys have been in progress for up to seven years at a marine-atmosphere exposure site near Daytona Beach, Fla. One of the most significant results...

...JT Ryder; FM Pickel The effect of temperature on stress corrosion cracking of high-carbon 300M high-strength steel in deionized water was investigated. Tests were conducted with wedge-opening-load specimens at 0, 23, and 90°C. Stress corrosion crack growth rates above the stress corrosion cracking...

... were noted not only in their cracking rates but also in their responses to similar loads and environments. Specimen thickness was found to have an important effect on stress corrosion susceptibility of the titanium alloys. Many coupons of specific titanium alloys had significant subsurface crack growth...

...O Jonas A new type of specimen for determining stress corrosion threshold stress is described. The specimen has a tapered gage length that provides longitudinal stress distribution with a maximum to minimum stress ratio of 1.85. After a constant load stress corrosion test, the surface...

...AA Hochrein, Jr; A Thiruvengadam An experimental investigation of stress corrosion cracking in metals is reproted for several alloy-corrodent systems. Internal damping measurements are made on the metals in the as-received condition and after they have been exposed to a corrosive environment. Data...
