Enhanced initial biodegradation resistance of the biomedical Mg-Cu alloy by surface nanomodification

Wen Zhang et al.

Summary: Mg-Cu alloys show promise as antibacterial implant materials, but their clinical applications are hindered by their high initial biodegradation rate. This study addresses this challenge by using nanotechnology to obtain a gradient nanostructured surface layer, resulting in a significantly lower initial biodegradation rate. The surface nanocrystallization and the fragmentation and re-dissolution of Mg2Cu particles contribute to the reduced degradation rate. Additionally, the nanomodified Mg-0.2 Cu alloy exhibits good antibacterial efficacy. Overall, this study creatively applies surface mechanical grinding treatment (SMGT) to produce a high-performance Mg alloy implant material.

Improvement of mechanical properties of hot extruded and aged Mg-Zn-Mn-Sn alloy through Dy addition

Hansong Xue et al.

Summary: The effects of different Dy additions on the microstructure and mechanical properties of Mg-6Zn-1Mn-3Sn (wt%, ZMT613) alloys were investigated. The study found that Dy addition resulted in significant grain refinement and the formation of new MgSnDy phases. A small amount of Dy (≤0.8 wt%) hindered the proportion of dynamic recrystallized grains during the hot-extrusion process and enhanced the basal texture of the alloy. MgSnDy high-temperature phase particles inhibited the recovery process and promoted the precipitation of the second phase. The ZMT613-0.2Dy alloy showed optimum mechanical properties after aging, with yield strength, ultimate tensile strength, and elongation reaching 336 MPa, 399 MPa, and 4.4%, respectively.
