Abstract
In this work two Fe - Mn - C alloys with different Mn contents were treated by equal-channel angular pressing (ECAP) in order to study the possibility of obtaining alloys with an increased degradation rate for the manufacture of biodegradable implants. Special attention was paid to the obtaining an ultrafine-grained alloys structure in a fully austenitic state and studying its effect on the corrosion rate, mechanical properties and biocompatibility in vitro. The X-ray analysis showed the formation of an austenitic structure in both alloys with the structural elements sizes of 100–250 nm after ECAP. For Fe-27Mn-C alloy ECAP resulted in significant increase in strength while maintaining satisfactory plasticity. The Fe-36Mn-C alloy samples destruction under tension occurs in the elastic region, which is associated with the α-Mn precipitation in the structure during ECAP deformation. The studied alloys were found to be hemocompatible. Reduced proliferation was noted on the Fe-36Mn-C alloy samples, indicating a non-specific biocidal effect of Mn. The alloys corrosion rates by weight loss method and potentiodynamic polarization analysis were studied. An increased corrosion rate of alloys after ECAP in comparison with the one of the course-grained counterpart, significantly exceeds the rate of corrosion of annealed iron.
