Description
In this sintering process, the tool or component is heated in a direct current passage, so that cycle times of a few minutes are possible. The use of direct current pulses results in an additional increase in sintering activity for many materials due to the processes taking place at the contact points of the powder particles (Joule heating, plasma formation, electromigration, etc.), so that significantly lower temperatures and/or pressures are required than with conventional hot pressing or sintering.
Nanomaterials can be sintered without significant grain growth
