Biodegradable Mg-Zn-Y alloys with long-period stacking ordered structure: optimization for mechanical properties.
To optimize the mechanical properties for biodegradable orthopedic implant, microstructures and tensile properties of Mg-Zn-Y alloys containing long period stacking ordered (LPSO) phase were investigated. For the as-cast Mg(100-3x)(Zn(1)Y(2))(x) (1 ≤ x ≤ 3) alloys, volume fraction of 18R LPSO phase increases with increasing the contents of Zn and Y. Mg(97)Zn(1)Y(2) alloy exhibits the optimal co...
متن کاملMicrostructures of Long-Period Stacking Ordered Phase of MgZnY Alloy
The microstructures of ¡-Mg, long-period stacking ordered (LPSO) phases, and kink bands in a MgYZn alloy were observed by transmission electron microscopy (TEM). The results showed that extruded Mg97Zn1Y2 alloy included different kinds of phases: 2H-Mg, 2H-Mg with many stacking faults, 14H and 18R. Kink bands tended to occur in areas where there were many intermetallic compounds. The element ...
متن کاملOrdered magnesium-lithium alloys: First-principles predictions
Magnesium-lithium Mg-Li alloys are among the lightest structural materials. Although considerable work has been done on the Mg-Li system, little is known regarding potential ordered phases. A first and rapid analysis of the system with the high-throughput method reveals an unexpected wealth of potentially stable low-temperature phases. Subsequent cluster expansions constructed for bcc and hcp s...
متن کاملMagnetic phase separation in ordered alloys
We present a lattice model to study the equilibrium phase diagram of ordered alloys with one magnetic component that exhibits a low temperature phase separation between paramagnetic and ferromagnetic phases. The model is constructed from the experimental facts observed in Cu32xAlMnx and it includes coupling between configurational and magnetic degrees of freedom that are appropriate for reprodu...
متن کاملDegradation behavior of Mg-based biomaterials containing different long-period stacking ordered phases
Long-period stacking ordered (LPSO) phases play an essential role in the development of magnesium alloys because they have a direct effect on mechanical and corrosion properties of the alloys. The LPSO structures are mostly divided to 18R and 14H. However, to date there are no consistent opinions about their degradation properties although both of them can improve mechanical properties. Herein ...
