“…This processing results in modification of surface layer of few mm thick and its refinement. As discussed before, a refined microstructure in case of Mg alloys leads to an improvement of the bio corrosion resistance [58] and surface mechanical properties [90][91][92].…”

“…In another effort, AZ31B Mg alloy was subjected to FSP followed by bio-corrosion evaluation [92]. Although authors did not discuss the microstructure evolution, they reported a marginal improvement in micro-hardness from 68 to 77 Hv, surprisingly a reduction in tensile properties for the processed samples was observed (yield strength lowered by 60 MPa and ultimate tensile strength lowered by 110 MPa while elongation remaining nearly identical).…”

Magnesium based alloys are attractive materials for biomedical applications as a result of their similar properties to the human bone and vital nature of the Mg ions during various functions of the human body. However, these materials suffer from poor corrosion resistance in chloride containing physiological environments. As a result, surface modification of biomedical alloys is needed to not only enhance the corrosion resistance but also biointegration characteristics. The current review article mainly focuses on beam and friction stir based techniques for surface processing of biomedical Mg alloys and composites. Each technique is further divided into sub-methods. Under the beam based processing, surface melting and bioceramic coating synthesis are discussed in detail. In the case of friction based methods, friction stir processing for grain refinement and techniques of surface modification to produce surface bioceramic composites are discussed. Furthermore, latest developments in the area of beam as well as friction stir additive manufacturing of biomedical Mg alloys and composites are elucidated. Lastly, possible directions for future progress and scaling up the lab level developments to actual applications in these materials processing areas for biomedical Mg alloys are provided.

“…Moreover, recent papers have shown that residual stresses imposed with surface treatments can affect the corrosion behavior of magnesium alloys [ 103 , 104 ]. Improvement in corrosion resistance has also been reported in magnesium alloys processed via friction stir processing [ 105 ] and multi-axial isothermal forging [ 106 ].…”

An Overview on the Effect of Severe Plastic Deformation on the Performance of Magnesium for Biomedical Applications

et al. 2023

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.

“…4, fine grain strengthening is an effective way to enhance the hardness of the alloy [48]. The material's hardness is inversely related to its grain size, with the smaller the grain size, the higher the microhardness [49]. Mg alloys have a higher Taylor index than other types of alloys, so grain refinement has a stronger strengthening effect on them [50].…”

In this study, AZ31 Mg alloy was processed by a new severe plasticity deformation methodology with multi-pass lowered temperature, and the deformation behavior and microstructure evolution were investigated by finite element method and electron back-scattered diffraction technique and hardness. The results show that with the increase of deformation pass, the strain gradually springs, and its interval distribution tends to homogenize. Meanwhile, the effective strain increases dramatically with the shear force sudden upgrade in the deformation process. Moreover, the new deformation technique can refine grain size remarkably. With the passes on, {10-12} tensile twins behavior and the pyramidal < c + a > slip are triggered more frequently, leading to the completeness of dynamic recrystallization (DRX) gradually, which weaken and disperse the basal texture obviously. Besides, the standard deviation of hardness is getting smaller, and the maximum can reach 78.40 HV on average, which can be attributed to the even large strain distribution, complete DRX, and the high geometrically necessary dislocation.
