“…The Fe diffraction peak width slightly increased due to the applied plastic deformation with HPT rotations, similar to previous SPD studies. [46,47] A similar shift of the peak was observed in a previous Fe-Al study. [48] SPD with milling process dissolved Al atoms in the Fe lattice with a slight angular shift in the Fe peaks.…”

Day by day biodegradable alloys and composites are getting more attention. Besides their competing material properties with traditional permanent implants, their harmless degradation in the body eliminates the need for a second surgery to remove the implant. Beyond other biodegradable materials such as Mg and Zn, Fe is known with high strength with low degradation rate. However there is still need to improve its biocompatibility. In this study, Fe‐Based composite was developed via solid state manufacturing route. %10HA/β‐TCP is selected as additive which is a biocompatible ceramic material and composition Ball Milled (BM). Afterwards the powders were consolidated via High Pressure Torsion (HPT) with 1‐5‐10 revolutions at room temperature. Crack‐free structures obtained even after 1 HTP rotation. Fe was in lamellar form around HA‐βTCP particles. With the increase of HPT rotation numbers, lath thickness decreased. After 10 HPT rotations 24% enhancement in density was observed that points more condensed structure. TEM observations show significant grain refinement after 1 HPT rotation, Fe grain size remains constant (∽300nm) up to 10 turns. UTS increased while degradation rate decreased after 5 HPT rotations. This works provides the potential of enhanced Fe‐based biomaterials for thinner and smaller implant designs.This article is protected by copyright. All rights reserved.
