XRD Characteristics as an Indicator of Mechanical Strength in Biodegradable Alloys
Abstract: The optical micrograph (OM) and X-ray diffraction (XRD) are examined in this work. The findings verify that all alloys contain α-Mg with MgZn2 secondary phases. Limited strengthening is indicated by the base Mg-5Zn alloy's larger crystallite size (8.27?25.62), lower lattice strain, and coarser grains (~99 ?m). The microstructure and strength capacity are greatly improved by alloying additions. The Ca-containing alloy has better structural stability and moderate grain refinement (~93 ?m). Defect strengthening is aided by the addition of Mn, which increases dislocation density and decreases grain size (~89 ?m). The alloy is containing Sr exhibits the smallest grain size (~76 ?m), largest lattice strain, finest crystallite size (7.79-12.62 nm), and greater precipitate volume. Overall, microstructural refinement and defect density increase in the order Mg-5Zn
