The results show that as a result of sintering at 1000 °C, no dissociation of Mn-Si additive particles embedded in the stainless steel matrix occurs. In contrast, sintering at 1050 °C develops a relatively homogeneous microstructure from the chemical composition viewpoint. The aforementioned phenomena are explained by liquation of the Mn-Si eutectic additive, thereby wetting of the main powder particles, penetrating into the particle contacts and pore zones via capillary forces, and providing a path of high diffusivity.EnglishElectron microscopyEnergy dispersive X-ray spectroscopyLocal chemical compositionMedical-grade stainless steelSinteringCapillary forceChemical compositionsCompositional homogeneityEnergy dispersive X ray spectroscopyHomogeneous microstructureNO dissociationParticle contactsPowder particlesAmorphous siliconElectron microscopyManganeseScanning electron microscopySiliconTransmission electron microscopyX ray spectroscopySinteringArticle10.1016/j.msec.2012.06.004
