    In this study, iron alloys containing 2 wt% palladium, silver or carbon were prepared using powder metalurgy. Microstructure, mechanical and corrosion properties in a simulated body fluid were characterized. Compared to pure iron, alloying slightly increased porosity (from 15% to - 18%) and decreased thje compressive modulus of elasticity (from 5.6 to 1.1-1.8GPa), compressive proof strength (from 145 to 113-127 MPa) and the Vickers hardness (from 63 to 23-37. Alloying with palladiuim and carbon enhanced (whereas silver lowered) the corrosion rate of iron in a simulated body fluid. Based on the obtained results, carbon and especially palladium appear to be suitable alloying elements for iron-based biodegradable materials.
