TL;DR
This study explores a new titanium alloy for hip implants that is biocompatible, has a low stiffness similar to bone, and shows good mechanical properties and corrosion resistance.
Contribution
The study introduces Ti-38Zr-11Nb alloy with a stable beta-phase and low Young’s modulus suitable for biomedical applications.
Findings
Ti-38Zr-11Nb alloy exhibits a stable β-phase and low Young’s modulus (81 GPa) after annealing.
The alloy shows improved tensile strength (628 MPa) and comparable corrosion resistance to titanium grade 2.
The material is biocompatible with no cytotoxic effects observed in mammalian cells.
Abstract
Hip joint implants are among the most prevalent types of medical implants utilized for the replacement of damaged joints. The utilization of modern implant materials, such as cobalt–chromium alloys, stainless steel, titanium, and other titanium alloys, is accompanied by challenges, including the toxicity of certain elements (e.g., aluminum, vanadium, nickel) and excessive Young’s modulus, which adversely impact biomechanical compatibility. A mismatch between the stiffness of the implant material and the bone tissue, known as stress shielding, can lead to adverse outcomes such as bone resorption and implant loosening. Recent studies have shifted the focus to β-titanium alloys due to their exceptional biocompatibility, corrosion resistance, and low Young’s modulus, which is close to the Young’s modulus of bone tissue (10–30 GPa). In this study, the microstructure, mechanical properties,…
