Pattern formation during current sintering (Simulation)

Conference Dates

March 10-15, 2019


Current sintering is becoming increasingly important for creating nanostructured materials from powders. Joule heating inside the sample enables the rapid densification necessary to preserve the nanostructure. However, the presence of electric fields and currents activates additional effects, such as inhomogeneous grain-growth and coarsening, thermoelectric effects, as well as dopant migration. In return, these effects influence the transport properties of the material during sintering which constitute feedback mechanisms that, ultimately, can lead to the formation of patterns.
