This research investigated the high-temperature microstructure, mechanical properties, and damping behavior of Fe-9Al-30Mn-1C-5Co (wt.%) alloy by means of electron microscopy, experimental model analysis, and hardness and tensile testing. Subsequent microstructural transformation occurred when the alloy under consideration was subjected to heat treatment in the temperature range of 1000-1150 °C: γ→(γ+κ). The κ-phase carbides had an ordered L'1 2-type structure with lattice parameter a=0.385nm. The maximum yield strength (σy), hardness, elongation, and damping coefficient of this alloy are 645 MPa, Hv 292, ~54%, and 178.5×10 -4, respectively. These features could be useful in further understanding the relationship between the biocompatibility and the wear and corrosion resistance of the alloy, so as to allow the development of a promising biomedical material.
