... quality products as expected. Nickel Alloys Weld Overlay Diffusion Rate Chemical Composition INTRODUCTION Weld overlay is a welding process where one or more metals with specific characteristics are applied to a base metal to improve desirable properties or to restore the original dimensions...

... research findings were validated by field trials where, by using the J55 tubing manufactured according to the new steel design (chemical composition and heat treatment), the lifetime improved significantly. The average Mean Time Between Failures (MTBF) corresponding to the field trials has increased...

...The chemical composition and mechanical properties of the plate and tube material are given in Table 1 . Tube and plate alloy are very different and especially in the plate material high amount of Sn and Fe were found. Both alloys still are within the specification for UNS R60702. Sample...

...According to earlier investigations [ 1 , 2 , 4 , 5 ], the permeation experiments presented in this paper were carried out using an electrochemical double cell according to Devanathan and Stachursky [ 3 ] shown in Figure 1 . The chemical compositions of the steels and that of the filler wire...

...) is of no consequence to barrier performance; and localized corrosion and microbially influenced corrosion are not expected to occur. To facilitate the discussion, Ti Grades 2, 5, 7, 9, 11, 12, 16, 17, 18, and 24 are included in this review. Titanium Chemical composition Mechanical property Repository environments...

... been measured. In addition to the already known effects of the pH value and the H₂S saturation, as the strongest influence of the chemical composition on hydrogen uptake the chloride content of the solutions has been identified. Again, it was found that the chemical composition...

... and elastomers. To establish the effects of molecular composition and structure of synthetic base fluids, a variety of organic base fluids were tested using several elastomers used in drilling equipment. Various test procedures were utilized to determine the effect of chemical composition of drilling fluids...

...The chemical composition of the steels is listed in Table 1 . As a specific item, reliable values of the effective diffusion coefficient of hydrogen in the investigated steel were evaluated which were assigned to a respective scatterband. In combination with the respective subsurface...
