Fast Consolidation of Iron Powders by Pulse Electric Current Sintering

Abstract:

Article Preview

Iron powders were successfully consolidated by a Pulse Electric Current Sintering (PECS) process in a short heating duration of 6 min. Microstructure and chemical composition of the sintered samples were studied by an optical microscope, scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX). Experimental results showed that both the densification of powders and inter-diffusion between elements were accelerated by increasing of the pulse peak. No noticeable grain growth was observed in the sintered samples. When the peak of pulse current increased, the density and transverse rupture strength of the sintered samples were improved.
