... influence of tensile stress and a corrosive environment on a susceptible material. Austenitic stainless steels including types 304L and 316L are susceptible alloys commonly used in nuclear weldments. An engineered residual stress field can be introduced into the surface of components that can reliably...

... will require corrosion resistance from both the base metal and the weldments. This paper provides corrosion data obtained in laboratory tests in various gas compositions at temperatures up to 1100°C. Special emphasis was given to the corrosion behavior shown by different welding consumables like FM28 (UNS...

...Abstract The effects of chloride concentration, fluoride concentration, pH, temperature, and weldments on the corrosion behavior of Ti Grade 7 (UNS R52400) were examined. It was noted that even at elevated temperatures (165 °C), the breakdown and repassivation potentials in chloride solutions were...

..., frequently by a considerable margin. An overview is given of the nature of remaining life assessment and examples given of methods developed for headers, seam-welded pipe and fired heaters. The more common poblems associated with weldments are also reviewed. remaining life power plant petrochemical plant...

... the same long term aging, the susceptibility to corrosion of both the base material and weldments remained unchanged. The effects of alloying elements on the resistance of the alloys to localized attack is discussed. nuclear waste repository nickel based alloys corrosion rate localized corrosion aging...

...The goal of this study was to evaluate the extent of marine microbially influenced corrosion (MIC) on a range of weldments representative of those employed in structural applications. Although numerous MIC investigations have been conducted on non-welded specimens in marine environments, more...

...Abstract Previous research in this laboratory demonstrated a direct correlation between alloy composition and corrosion susceptibility of stainless steel and Ni-Cr-Mo alloy weldments exposed to lake water augmented with sulfate reducing bacteria (SRB). It was shown that lake water containing...

... of the material around weldments throughout the system. Due to the non-equilibrium solidification nature of weldments, the electrochemical properties of the weld may be different than those of the surrounding base material due to changes in surface texture, solute segregation, second phase precipitation...

...Carbon steel injection water oxygen chlorine preferential corrosion weldments INTRODUCTION Seawater injection into the reservoir is frequently used for offshore production of oil to extend the production lifetime and to increase the total oil production from the reservoir. To prevent...

... corrosion. The metabolic processes of the microorganisms can also; ¹ SUMMARY ○ MIC often occurs near weldments in austenitic stainless steels. The pitting may be in the weld metal, heat affect zone, along the fusion line, or in the base metal near the weld, or in combinations. Either or both...

... is presented with a strong argument favouring automated time-of-flight-diffraction (TOFD) ultrasonic inspection of susceptible pressure vessel weldments. Amerada Minerals Corporation of Canada Ltd. conducted a detailed laboratory study in conjunction with CorTest Laboratories (Houston, Texas), to study...
