| Abstract Scope |
ERW is a well-established technology for the manufacture of oil country tubular products. It is well understood that an artifact of ERW welding is a thin decarburized band running along the bond line. In the presence of bond line flaws, this band can act to locally reduce fracture toughness. To improve this bond line fracture toughness, in-line annealing practices have been investigated for homogenizing this bond line. Work here was done using ICME techniques. In this study, carbon diffusivity during annealing has been evaluated using computational microstructure prediction tools. Runs from the computational tools were organized using design of experiments (DOE) techniques. Data collected from the individual runs then mapped using linear functions for subsequent microstructural analysis. Carbon back-diffusion was estimated based on a Zener type analysis. These results then were used to assess degrees of homogenization associated with different decarburized bond widths as well as annealing time and temperatures. |
