      Oral Presentation

      Under certain conditions of oxygen shortage and high temperatures as could occur after coiling a hot-rolled strip, alloying elements can diffuse and oxidise preferably along grain boundaries, causing a depletion zone of solute alloying elements in the surface near region. When oxides are present along grain boundaries, pickling can alter surface topography by selective dissolution of these...
