In the present investigation the effect of high voltage and low frequency current pulses on Ni powder compacts and on alloys like Ni80Si 20 or Ni95Si5 are investigated. The pulse application on ball milled Ni powder compacts and on Ni80Si 20 result in a further increase in density. This suggests that the SPS and EDC technique can be used as an alternative method for the sintering of nano-materials and for the densification of nano particles but with the simultaneous application of pressure.
