Abstract Scope |
The quality and functionality of welds for use in the various industries are dictated by their mechanical properties which are related to their microstructures and are influenced by the weld processing parameters. Thus, there is a need to quantitatively characterize the microstructure of welds and correlate these to weld processing conditions. In this work, we present a new technique to quantitatively characterize the grain size, grain shape, and grain boundary curvature of welds. We will show that this technique can be used to quantitatively describe the spatial variations in these characteristics as a function of weld processing conditions.
