Material process involves the knowledge of industrial processes, reaction thermodynamics, reaction kinetics, transport phenomena. In view of the heterogeneous reaction nature of most of the processes, it also needs the research of the interfacial phenomena.
One specialist technique used by the Unit of Process is electrolytic extraction of non-metallic inclusions from steels, together with scanning electron microscopy. This allows investigation of the inclusion in three dimensions and can overcome some of the limitations with two-dimensional investigation on polished samples. Investigations have been performed on inclusions such as alumina, magnesia, calcia, zirconia, rare earth metal oxides, oxy-sulfides and various nitrides and carbides. The Unit of Processes is one of the centres that is most active with this method. We have reported this technique in 30 academic publications and 35 conference presentations since 2008.
