“…in Figure 11. It should be noted that the present extruded lowalloyed alloy has a better YS (YS = 201 MPa) than that of the recently reported extruded Mg alloys such as Mg-6Zn (YS = 170 MPa) (Zhao et al, 2017), Mg-2Sn-0.5Ca (YS = 188 MPa) (Laser et al, 2008), Mg-3Sn-1Zn-0.5Mn (YS = 162 MPa) (Hou et al, 2016), and Mg-3Nd-0.2Zn-0.4Zr (YS = 145 MPa) (Ma et al, 2014). In addition, the extruded alloy with an average DRXed grain size of 2.32 µm has a favorable corrosion resistance compared to the other fine-grained extruded alloy.…”

An extruded low-alloyed Mg-Bi-Al-Zn alloy combining excellent tensile properties (YS = 201 MPa, EL = 29. 4%) with high corrosion resistance (P i = 0.14 mm/a) for biomedical application is successfully developed in this study. The extruded alloy is mainly composed of dynamic recrystallized (DRXed) grains (2.32 ± 0.12 µm) and strongly textured coarse non-DRXed grains, as well as certain nano-scaled Mg 3 Bi 2 precipitates (135.68 ± 27.86 nm). Note that most basal planes for non-DRXed grains are preferentially distributed parallel to the extrusion direction. The study explored the dependences of the properties and relevant mechanisms of the studied alloy on its microstructural characteristics in terms of grain size, grain orientation, and precipitates.

As promising biodegradable materials with nontoxic degradation products, magnesium (Mg) and its alloys have received more and more attention in the biomedical field very recently. Having excellent biocompatibility and unique mechanical properties, magnesium‐based alloys currently cover a broad range of applications in the biomedical field. The use of Mg‐based biomedical devices eliminates the need for biomaterial removal surgery after the healing process and reduces adverse effects induced by the implantation of permanent biomaterials. However, the high corrosion rate of Mg‐based implants leads to unexpected degradation, structural failure, hydrogen evolution, alkalization, and cytotoxicity. To overcome these limitations, alloying Mg with suitable alloying elements and surface treatment come highly recommended. In this area, open questions remain on the behavior of Mg‐based biomaterials in the human body and the effects of different factors that have resulted in these challenges. In addition to that, many techniques are yet to be verified to turn these challenges into opportunities. Accordingly, this article aims to review major challenges and opportunities for Mg‐based biomaterials to minimize the challenges for the development of novel biomaterials made of Mg and its alloys.

“…However, there is much more microgalvanic corrosion as the concentration of Al and Zn increases, leading to poor corrosion resistance. Further, Sn has been attracting more and more attention because of its grain refinement and reduction of the hydrogen evolution rate of Mg alloys [20,21]. Therefore, it is necessary to find one low-cost alloy system to improve the corrosion resistance performance of Mg alloys.…”

The effect of Sn addition on the microstructure and corrosion behavior of extruded Mg–5Zn–4Al–xSn (0, 0.5, 1, 2, and 3 wt %) alloys was investigated by optical microscopy (OM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), electrochemical measurements, and immersion tests. Microstructural results showed that the average grain size decreased to some degree and the amount of precipitates increased with the increasing amount of Sn. The extruded Mg–5Zn–4Al–xSn alloy mainly consisted of α-Mg, Mg32(Al,Zn)49, and Mg2Sn phases as the content of Sn was above 1 wt %. Electrochemical measurements indicated that the extruded Mg–5Zn–4Al–1Sn (ZAT541) alloy presented the best corrosion performances, with corrosion potential (Ecorr) and corrosion current density (Icorr) values of −1.3309 V and 6.707 × 10−6 A·cm−2, respectively. Furthermore, the corrosion mechanism of Sn is discussed in detail.
