عنوان انگلیسی Influence of Machining Parameters on the Structural Changes of Bio-Titanium Dental Implants
چکیده انگلیسی مقاله This study investigates the impact of machining parameters on the structural changes of dental implants made from bio-titanium alloy (Ti6Al4V-ELI). The implants were designed based on a commercial model and machined under various conditions. The study specifically examines the influence of spindle rotation (S) and cutting depth (Q) on grain size, micro strain, dislocation density, and texture parameter. X-ray diffraction (XRD) was used to analyze the samples, with X’Pert and Maud software employed for evaluating XRD peak broadening and quantifying α and β phases. The Williamson-Hall method was used to investigate microstructural features such as crystallite size and results showed 153.2, 154.06, 15.72, 77.03, and 22.65 nm for as-received, sample A, B, C, and D. The study also examined changes in texture qualitatively by comparing the intensity of the peaks of the XRD pattern. The findings provide valuable insights in order to optimizing the manufacturing process of medical implants, contributing to enhanced performance and longevity in a biological environment. According to the results obtained from the XRD pattern of the samples, it can be said that due to the machining process and changing the parameters, the peak intensity and position for both phases of the alloy were changed compared with those in the as-received sample. Also, dislocation density was affected by the machining parameters which the interaction plot was used to investigate the trend of these effects. The different T.P (texture parameter) values (both less than and greater than 1) indicated that the texture was changed as a result of the machining process.
