title = "Microstructural studies of friction stir welded Zircaloy-4",
abstract = "Friction stir welding was applied to a zirconium alloy, Zircaloy-4, using a Co-based alloy tool. Zircaloy-4 was successfully welded, and a shiny, smooth surface was obtained. FSW produced a defect-free weld with a fine equiaxed grain structure in the stir zone, which caused an increase in hardness.",
