Description


 

The point of this sintering is the internal heating source. The sample is located inside a die-electrode system that allows uniaxial pressure and crossed by a pulsed or not electric current. According to the system electric properties, the heating will be broughtby the die or inside the sample itself .

The applied current ( DC or pulsed ), high heating rate and uniaxial pressure allow the synthesis of materials with characteristics (Relative density - Grain size - Vickers hardness - Fracture thoughness) not reached with conventionnal heating source (classical furnace).
