Abstract
Influences of sintering condition, particle size, alloying powders on the resistance-sintering process of titanium powder were analyzed.
The change of electric resistance during sintering depends upon the set up current level, applied pressure, particle size, pretreatment of powder and addition of alloying powders of Mo, Cr, and Al. The electric resistance at the same period becomes smaller when the set up current level, pressure and particle size become larger and also the oxygen content of the powder lowers. Addition of Mo or Cr powder to Ti powder decreases the electric resistance during sintering but addition of Al powder increases it.
