The aim of this paper is to map the corrosion fatigue characteristics of Ti-6Al-4V alloy through the evaluation of the corrosion fatigue initiation and failure mechanisms. The study included the effect of the stress concentration factor at very high Kt values and the role of different inert or corrosive environments. This alloy is widely used in naval-structures and aero-engine communities and ...

9 In some sour reservoirs and tertiary oil recovery blocks, SO42in solution can cause the corrosion 10 and corrosion fatigue of the sucker rods. In this paper, the corrosion behaviors of super-strength 11 sucker rod FG20 (16Mn2SiCrMoVTiA) steel in the well fluid are investigated by electrochemical 12 measurements, and electron probe micro-analyzer (EPMA) analysis. The results show that FG20 ste...

All steels contain some amount of dissolved gases such as oxygen, hydrogen and nitrogen of which nitrogen is effective in improving the mechanical and corrosion properties of stainless steels if it remains in solid solution or precipitates as very fine and coherent nitrides or carbo-nitrides with iron or alloying elements. When nitrogen is added to austenitic steels it can simultaneously improv...

Corrosion fatigue (CF) tests were carried out on bulk glassy Zr52.5Cu17.9Al10Ni14.6Ti5 (Vitreloy 105) samples under load-controlled three-point bending conditions with a load ratio of R = 0.1 in 0.01 M Na2SO4 + 0.01 M NaCl electrolyte. During cyclic testing, the bar-shaped specimens were polarized in situ at constant potentials and the current was monitored. Three different anodic potentials wi...

The ability to map plastic deformation around high strain gradient microstructural features is central in studying phenomena such as fatigue and stress corrosion cracking. A method for the visualization of plastic deformation in electron back-scattered diffraction (EBSD) data has been developed and is described in this article. This technique is based on mapping the intragrain misorientation in...

The proposed work will combine chemical kinetics and hydrodynamics in target and test-loop lead-bismuth eutectic (LBE) systems to model system corrosion effects. This approach will result in a predicative tool that can be validated with corrosion test data, used to systematically design tests and interpret the results, and provide guidance for optimization in LBE system designs. The task includ...
