Field assisted sintering technique (FAST) / spark plasma sintering (SPS)

The basic idea of sintering with electric current going through the mold is quite old. Resistance heating of cemented carbide powders was patented by Tayler as early as 1933. This method is currently undergoing renewed interest. Current can be pulsed or unpulsed DC or AC. Spark plasma sintering (SPS) is a common name for this technique, however, it is technically
