Abstract
Field Assisted Sintering Technique (FAST) or Spark Plasma Sintering (SPS) is a hot consolidation method which is receiving widespread research and development recently. FAST/SPS utilizes the pulsed DC electrical current to activate the sintering process for the consolidation of various advanced materials. This current research is targeting on modeling and simulation of electrical and thermal field related to this special hot consolidation process. There is also effort to extract material constitutive parameter enabling the modeling of material densification process. Tungsten, vanadium carbide, and copper are the selected materials being researched. With extremely short processing time as one of the most attractive advantages, this technology is suitable for a wide range of applications including energy, bio-medical, aerospace, electronics and optics.
