The powders were blended in a three dimensional blender for 20 min and compacted in a die under 500 MPa by using an one directional press. Sinterability and mechanical properties of the samples with different carbon content were investigated. Sintering process was carried out on a belt furnace with flame curtain in dissociated ammonia atmosphere. Block samples produced were suitable for ASTM B-312 transverse rupture strength test apparatus and were tested with 0.050 kN/s velocity in a press under 100 g load. It was found that graphite amount up to 2 wt pct increased the contact area of particles and acted as a lubricant to affect the sintering behavior positively. The results indicated that the samples containing up to 5 wt pct showed good sintering behavior and also good hardness due to an increase in pearlite amount. However, the samples containing higher amount of graphite (more than 5 wt pct) affected the sintering behavior negatively due to the settlement of free graphite around the iron powders, which resulted in a decrease in the hardness and transverse rupture strength.eninfo:eu-repo/semantics/closedAccessGraphiteIronPowder metallurgySinteringTransverse rupture strengthEffect of different amounts of graphite on the sintering and transverse rupture properties of powder metal partsArticle2-s2.0-337465544004223Q141922
