Magnesium (Mg) has attracted considerable attention as a biodegradable material for medical implants owing to its excellent biocompatibility, mitigating long-term toxicity and stress shielding. Nevertheless, challenges arise from rapid degradation low corrosion resistance under physiological conditions. To overcome these challenges, titanium (biocompatibility resistance) been integrated into Mg. The incorporation of significantly improves mechanical properties, thereby enhancing performance in biological settings. Mg–Ti alloys are produced through alloying spark plasma sintering (SPS). SPS technique transforms powder mixtures bulk materials while preserving structural integrity, resulting enhanced resistance, particularly Mg80-Ti20 alloy simulated body fluids. Moreover, revealed no more when assessed on pre-osteoblastic cells. Furthermore, the ability Mg–Ti-based create composites with polymers such PLGA (polylactic-co-glycolic acid) widen their biomedical applications by regulating ensuring pH stability. These promote temporary orthopaedic implants, offering initial load-bearing capacity during healing process fractures without requiring second surgery removal. address scalability constraints, further research is necessary investigate additional consolidation methods beyond SPS. It essential evaluate relationship between loading confirm adequacy environments. This review article highlights importance characterization evaluation alloys, reinforcing applicability fracture fixation various implants.

The microstructural, mechanical and corrosion properties of low-alloyed Mg-Zn-Ca alloys with different Zn/Ca atomic ratios were investigated. results show that the microstructure extruded Mg-1Zn-0.3Ca (ZX1.0) alloy mainly consists α-Mg Ca2Mg6Zn3 phases a small amount Mg2Ca phase. In contrast, phase disappears in Mg-1.4Zn-0.3Ca (ZX1.4), Mg-1.8Zn-0.3Ca (ZX1.8) Mg-2.3Zn-0.5Ca (ZX2.3). are distributed along extrusion direction, showing irregular particle shapes banded particles. Meanwhile, grain size is reduced gradually increase Zn Ca contents, decreasing from 1.87 μm ZX1.0 to 1.28 ZX2.3 alloy. Fine strengthening second-phase yield strength ultimate tensile addition, when ratio same, total elemental content dominates effect on properties. When increasing ratio, potential difference between Mg matrix increased, resulting an galvanic corrosion. negative volume fraction second positive fine determine performance together. Therefore, ZX1.8 exhibits best resistance, 0.14 mm/y.

Mg-6Zn-0.5Mn as a medical magnesium alloy has good biomechanical properties and corrosion resistance, but fracture internal-fixation material, its strength, toughness, resistance still need to be improved. In this paper, the element Sr, having biocompatibility, is used an element. The effects of different Sr contents (0 wt.%, 0.3 0.6 0.9 1.2 wt.%) on microstructure, rolled were studied. results are follows. can influence recrystallization process. When content wt.% matrix exhibits both non-recrystallized regions fine recrystallized regions. reaches region decreases significantly, grains develop into equiaxed grains. With increase content, elongation decreases. At optimum value, with average rate 0.75828 mm/y.
