A high-pressure torsion (HPT) with a number of revolutions (n) up to 10 and an advanced method accumulative HPT (AccHPT), n = subsequent post-deformation annealing (PDA) at 500 600 °C, were applied biodegradable Fe-30Mn-5Si (wt.%) alloy. The effect HPT, AccHPT PDA on the microstructure, phase composition, microhardness electrochemical behavior in Hanks’ solution was studied. 1 5 resulted forming mixed submicrocrystalline (SMCS) nanocrystalline (NCS)structure, while AccHPT, predominant NCS...
Abstract Metastable near‐beta Ti‐21.8Nb‐6Zr and Ti‐19.7Nb‐5.8Ta (at%) alloys were subjected to a thermomechanical treatment comprising cold rolling (CR) with true strain of e = 0.3 post‐deformation annealing (PDA) in the 500–900°C temperature range ensure superelastic behavior which is important for bone implants. It was found that PDA resulted formation about 1–2 μm‐thick oxide layer on Ti‐Nb‐Zr Ti‐Nb‐Ta alloy samples; mainly composed TiO 2 , rutile anatase modifications. The structure,...
The paper compares the coatings produced by plasma electrolytic oxidation (PEO) on commercially pure titanium and a novel superelastic alloy Ti-18Zr-15Nb (at. %) for implant applications. PEO were both alloys in identical pulsed bipolar regime. properties of examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive spectroscopy (EDX), potentiodynamic polarization (PDP), electrochemical impedance (EIS). process kinetics was modeled based Avrami theorem...
The Fe-Mn-Si shape memory alloys are considered promising materials for the biodegradable bone implant application since their functional properties can be optimized to combine bioresorbability with biomechanical and biochemical compatibility tissue. present study focuses on fatigue corrosion behavior of thermomechanically treated Fe-30Mn-5Si (wt %) alloy compared conventionally quenched because this important functionality aspect has not been previously studied. Hot-rolled water-cooled,...
The aim of the present work was to study corrosion and electrochemical behavior Ti-22Nb-6Ta (at. %) superelastic alloy in comparison with commercially pure titanium (cp-Ti) under simulated service conditions load-bearing bone implants, i.e. cyclic load body fluid environment. Open circuit potential (OCP) measurements were carried out on wire samples Hank's solution at 37 °C applying bending (maximum induced strain 0.8%) up 75×103 cycles or sample failure. It is shown that superior cp-Ti...
Fe-30Mn-5Si alloy subjected to a compression test at various deformation temperatures ranging from 350 900 °C with strain rate of 1 s−1 are studied. It was found that the exhibits high resistance dynamic recrystallization process in whole studied range temperatures. There no differences structure formation zone action tangential tensile stresses and peripheral central zones localized compressive stresses. The room-temperature X-ray diffraction study shows presence single-phase state (FCC...
