by an intensive electric current. A proper coupling of pulse current and subsequent constant current sintering facilitates the high relative density and sound mechanical properties of the alloys. 2) 15 h... that of the single pulse current sintering, owing to its higher mean value. In case of constant current sintering, a higher sintered density of 16.92 g/cm3 can be achieved by intensifying electric current. In spite......
