... of corrosion are studied; these are uniform corrosion, pitting corrosion and stress corrosion cracking. Failure frequency is estimated by fitting historical failure data of pipeline into either a homogenous Poisson process or power law. The consequences of corrosion attack is calculated in terms of economic...

... resistance property to fine grain steel is very important. In this study, Stress Corrosion Cracking test was done on specimens of the fine grain steel and conventional steel. Afterwards fracture surfaces were observed with SEM (Scanning Electron Microscope) and the residual stresses under the fracture...

... ABSTRACT Laser peening technology has matured into a fully qualified production process that is now in routine and reliable use for a range of aerospace alloys. The technology is capable of extending the fatigue life and stress corrosion cracking life of components, and will enable designers...

... was developed to assess fatigue strength of fillet welded joint to reduce cyclic time and costs. Stress corrosion cracking susceptibility was also evaluated in a sour environment using C-rings and Slow Strain Rate Testing (SSRT). Based on the test results, an age hardened Ni-base alloy was selected for sour...

... and good SCC resistance. INTRODUCTION The Al-Zn-Mg-Cu system alloys (7000 series) is well known as an aluminum alloy with both of excellent workability and mechanical properties. In this series of the alloys, the stress corrosion cracking (SCC) becomes to be lower with increasing the strength...

... transition modulus toughness GFRP products fracture easily in an acidic environment under a relatively low load due to the stress corrosion of the glass fiber. However, the stress corrosion of GFRP does not take place, without a load, or beneath a certain stress limit. The paper describes a study being made...

... ABSTRACT: Stress corrosion cracking tests were conducted by using high strength steel SNCM 439 in 3_5%NaCI solution under various experimental conditions. The crack shapes obtained in these tests were analyzed by fractal method. The results obtained were summarized as follows: The crack growth...
