عنوان انگلیسی Enhanced Titanium Structures via Spark Plasma Sintering and Shear Extrusion: XRD Analysis of Mechanical and Biocompatibility Properties
چکیده انگلیسی مقاله Aims: This study aims to investigate the effects of severe plastic deformation (SSE) following spark plasma sintering (SPS) on the microstructural and mechanical properties of commercially pure titanium for advanced biomedical applications.
Materials & Methods: Commercially pure titanium samples were first fabricated using SPS at 900°C and subsequently subjected to SSE at room temperature. Microstructural analyses were performed using Williamson-Hall XRD calculations to evaluate grain size. Mechanical properties, including hardness and tensile strength, were assessed to determine the influence of the SSE process.
Findings:The grain size decreased significantly from 60.2 nm in the SPS-processed sample (first sample) to 27.9 nm in the SSE-processed sample (second sample). Hardness increased from 373.2 HV in the first sample to 411 HV in the second sample, compared to the base titanium hardness of 315 HV. These findings demonstrate the SSE process's ability to refine microstructure and enhance mechanical properties.
Conclusion: The refined microstructure and increased surface free energy in the SSE-processed titanium enhance its potential for biomedical applications. The improved hardness and mechanical strength, combined with superior biocompatibility, are expected to accelerate osseointegration and bone growth, ensuring reliable performance in load-bearing implants. This makes SSE-processed titanium a promising candidate for advanced medical implants.
