Estimation of Atmospheric Corrosion of High-Strength, Low-Alloy Steels
This data analysis was undertaken to investigate the weatherability of steels whose compositions do not fall in the range of ASTM Standard G101, Estimating the Atmospheric Corrosion Resistance of Low-Alloy Steels (1). This standard was developed to estimate the corrosion resistance of low-alloy weathering steels from chemical composition data and from actual atmospheric exposure tests. This sta...

متن کاملHigh frequency fatigue crack propagation behavior of a nickel-base turbine disk alloy
Fatigue crack propagation tests were conducted on the powder metallurgy nickel-base superalloy KM4 at room temperature. Two different heat treatments were investigated, one which produced a relatively coarse grain size around 55 μm, and another which produced a very fine grain size around 6 μm. Tests were conducted at 50 Hz and 1000 Hz in an advanced servohydraulic testing machine at R-ratios b...
متن کاملHigh-Strength Bolt Corrosion Fatigue Life Model and Application
The corrosion fatigue performance of high-strength bolt was studied. Based on the fracture mechanics theory and the Gerberich-Chen formula, the high-strength bolt corrosion fracture crack model and the fatigue life model were established. The high-strength bolt crack depth and the fatigue life under corrosion environment were quantitatively analyzed. The factors affecting high-strength bolt cor...
متن کاملThe Growth of Small Corrosion Fatigue Cracks in Alloy
The corrosion fatigue crack growth characteristics of small (>35pm) surface and corner cracks in aluminum alloy 7075 is established. The early stage of crack growth is studied by performing in situ long focal length microscope (500X) crack length measurements in laboratory air and 1% NaCl environments. To quantify the “small crack effect” in the corrosive environment, the corrosion fatigue crac...
