Abstract

Pure aluminum (Al) powder was sintered by means of a pulse electric current sintering (PECS) process at various pulse frequencies. The effects of pulse frequency on the density, electrical resistivity and tensile properties of the compacts were investigated. The results showed that the effects were not significant. From the activation energy calculation in the sintering process and scanning electron microscopy observation of compacts and transmission electron microscopy observation of interfaces between powder particles, the pulse frequency effects on PECS process and microstructure were not observed.
