Abstract Scope |
Neutron scattering is one of few characterization methods that allow for non-destructive bulk characterization of micro- and nanostructures in hard metals that contain heavy elements such as tungsten. The non-destructive nature of neutron scattering can be applied to follow structural evolution in real-time during processing under relevant technical conditions. In the present work we elaborate on the use of in-situ neutron scattering to enhance the mechanistic understanding of structural evolution during high-temperature synthesis of carbides and heat treatment of hard metals as well as during high-temperature deformation of hard metals. In-situ small-angle neutron scattering and/or diffraction are applied depending on the structural scale of interest. The results obtained assist the interpretation of the underlying mechanisms of grain coarsening and inhibition during heat treatment of hard metals and creep property enhancement in doped hard metals at application temperatures as well as phase decomposition in hard metal relevant carbides. |
