Abstract

Gas atomized Cu powder is added to Iron powder in varying amounts and mixed in a V-type mixer for 30 minutes at 15 rpm. As lubricant 1 wt% Acrawax C is used. The mixtures are compacted at 600 MPa to form TRS (Transverse Rupture Strength) samples with dimensions 6,35*12,8*31,8 mm. The samples are sintered using conventional and microwave furnaces for 30 minutes at 1150 °C under 90% N2 -10% H2 atmosphere. The microstructure of sintered specimens and Cu dispersion in Fe are observed by SEM and EDS, and the strength is determined by TRS tests.
