The 20 different PM compacts compositions were prepared with a 0.8. wt.% ratio of zinc striate as the lubricant. The dimension of compacts were 10. ×. 10. ×. 55. mm. All the compacts were pressed at 600. MPa and, sintered at 1120. °C for 30. min using a conventional sintering furnace and then boronizing, steaming and carbo-nitriding heat treatments were applied. The results of all compacts for the bending test, microstructure images and HV microhardness results were compared. As a result of the experiments, it was concluded that, the highest bending strength was obtained at carbo-nitrided samples, the highest surface hardness was measured at boronized samples and all these heat treatments increase the densities of iron based samples. © 2014 Elsevier Ltd.EnglishBending strengthIronMechanical propertiesSinteringBoronizingConventional sinteringIron-basedNitridedSurface hardnessPowder metalsArticle10.1016/j.matdes.2014.09.015
