There has been a great interest in evaluating the potential of severe plastic deformation (SPD) to improve the performance of magnesium for biological applications. However, different properties and trends, including some contradictions, have been reported. The present study critically reviews the structural features, mechanical properties, corrosion behavior and biological response of magnesium and its alloys processed by SPD, with an emphasis on equal-channel angular pressing (ECAP) and high-pressure torsion (HPT). The unique mechanism of grain refinement in magnesium processed via ECAP causes a large scatter in the final structure, and these microstructural differences can affect the properties and produce difficulties in establishing trends. However, the recent advances in ECAP processing and the increased availability of data from samples produced via HPT clarify that grain refinement can indeed improve the mechanical properties and corrosion resistance without compromising the biological response. It is shown that processing via SPD has great potential for improving the performance of magnesium for biological applications.

“…Severe plastic deformation (SPD) is a newly developed manufacturing and forming process, which introduces ultralarge plastic strain to Mg alloys to create a fine-grained or ultrafine-grained microstructure [79][80][81][82]. SPD process is an Grain size / μm Frequency / % important method to develop Mg alloys with high strength and high ductility, including equal channel angular pressing (ECAP), accumulative roll bonding (ARB), and high-pressure torsion (HPT).…”

Magnesium (Mg) alloys, as the lightest metal engineering materials, have broad application prospects. However, the strength and ductility of traditional Mg alloys are still relativity low and difficult to improve simultaneously. Refining grain size via the deformation process based on the grain boundary strengthening and the transition of deformation mechanisms is one of the feasible strategies to prepare Mg alloys with high strength and high ductility. In this review, the effects of grain size on the strength and ductility of Mg alloys are summarized, and fine-grained Mg alloys with high strength and high ductility developed by various severe plastic deformation technologies and improved traditional deformation technologies are introduced. Although some achievements have been made, the effects of grain size on various Mg alloys are rarely discussed systematically and some key mechanisms are unclear or lack direct microscopic evidence. This review can be used as a reference for further development of high-performance fine-grained Mg alloys.

“…4 To fulfil this requirement, researchers have developed various techniques and materials over the years to produce biomaterials with superior characteristics.. 5,6 Magnesium and its alloys are highly desirable materials for biomedical purposes due to their lightweight nature, lower density, near-bone elastic modulus and degradability in the cellular environment. 7,8 Furthermore, studies have shown that magnesium can significantly aid in the acceleration of bone formation. 9 Nevertheless, using pure magnesium and commercial alloys for biomedical purposes has certain limitations, including a high corrosion rate, lower strength for pure magnesium and potential health issues associated with alloying elements like aluminium in commercial magnesium alloys such as AZ91 and AZ31.…”

In this study, cyclic extrusion compression angular pressing-forward extrusion was employed to develop binary magnesium-based multiphase alloys, and subsequently analysed the microstructural, mechanical and corrosional properties of the resulting samples. The findings demonstrate that the inclusion of alloying elements in the multiphase alloys significantly enhances their microstructural, mechanical and corrosional properties. Compared to pure Mg samples fabricated using the same method, the multiphase alloys produced by this technique exhibit finer grain structures. Mechanical analysis indicates that these multiphase alloys possess higher yield and ultimate strength compared to pure magnesium. Corrosion testing reveals that all produced alloys outperform pure magnesium in various aspects. Particularly, Mg–1Zn and Mg–1Mn alloys exhibit exceptional corrosion resistance in immersion, mass loss and polarisation tests.
