“…The CR of Zn, Zn–4Mn and Zn–24Mn was 2.71, 0.72 and 0.02 mm/y, respectively. [ 139 ] SPS Porous Zn Sintered at 300 °C for 10 min under 5 MPa at a heating rate 100 °C/min in an argon atmosphere + extrusion at 300 °C with an extrusion ratio of 10 and at an extrusion rate of 0.3 mm/s. Materials prepared from coarse Zn powders (size ~ 600–850 μm) are designated as CP, while that from fine powders (size ~ 40–100 μm) are as FP.…”

“…Interestingly, the usage of R3 on the Zn-0.34Mn and Zn-0.76Mn alloys gave them extremely high elongation, e.g., 88.8% and 94.0% at RT, respectively ( Table 5 ). The microstructures and mechanical properties of PM-processed Zn–4Mn and Zn–24Mn alloys were investigated by Bagha et al [ 139 ]. The microstructures of these alloys contained nano-sized crystallites (>40 nm) and the secondary phases of MnZn 3 and MnZn 13 , which enhanced the compression strength, elastic modulus and micro-hardness of these alloys.…”

“…However, in another study, they reported a reduction of CR in Zn–4Fe alloy with respect to pure Zn in the same corrosion medium owing to the passivation effect of corrosion products [ 272 ]. Addition of Mn was noted to shrink the CR of pure Zn, such as, addition of 4 and 24 wt% Mn in pure Zn dropped the CR of Zn more than 3 and 100 times, respectively, which was ascribed to finer microstructure and the formation of a fewer intermetallic compound [ 139 ].…”

Biodegradable metals (BMs) gradually degrade in vivo by releasing corrosion products once exposed to the physiological environment in the body. Complete dissolution of biodegradable implants assists tissue healing, with no implant residues in the surrounding tissues. In recent years, three classes of BMs have been extensively investigated, including magnesium (Mg)-based, iron (Fe)-based, and zinc (Zn)-based BMs. Among these three BMs, Mg-based materials have undergone the most clinical trials. However, Mg-based BMs generally exhibit faster degradation rates, which may not match the healing periods for bone tissue, whereas Fe-based BMs exhibit slower and less complete in vivo degradation. Zn-based BMs are now considered a new class of BMs due to their intermediate degradation rates, which fall between those of Mg-based BMs and Fe-based BMs, thus requiring extensive research to validate their suitability for biomedical applications. In the present study, recent research and development on Zn-based BMs are reviewed in conjunction with discussion of their advantages and limitations in relation to existing BMs. The underlying roles of alloy composition, microstructure, and processing technique on the mechanical and corrosion properties of Zn-based BMs are also discussed.

“…Consequently, dislocation movement was enhanced with higher Mn content resulting in an increase of the  f at the expense of the tensile strength. Sotoudeh Bagha et al [89] prepared Zn-xMn (x = 4, 24 wt. %) alloys via powder metallurgy and found a microstructure consisting of nano-sized crystallites with MnZn 13 and MnZn 3 second phases, which contributed to an increased compression strength.…”

“…Moreover, this structure can provide both high strength and ductility, which are desirable for stent applications. Mechanical alloying is a method to produce fine grain biodegradable Fe-based [22] and Zn-based [23] metals. Srinivasarao et al [24] produced a bimodal structure of ferrite steel composed of fine grains (<100 nm) and micrometer grains via mechanical alloying and Spark Plasma Sintering (SPS) process.…”

Researchers in biodegradable metals have been putting efforts to accelerate the corrosion of ironbased biodegradable metals. These include by alloying iron with manganese and noble elements such as silver, but further increase to the corrosion rate is still needed. In this study, a set of bimodal nano/microstructured Fe-30Mn-1Ag alloys was prepared through mechanical alloying and spark plasma sintering. The alloys were characterized and tested for their corrosion behavior in Hanks' solution at 37 o C and for their mechanical properties. The bimodal-structured alloy possessed a mixture of austenitic (γ-FeMn) and ferritic (α-Fe) phases, while the nano-and macro-structured ones were essentially composed of γ-FeMn and α-Fe phases, respectively. Addition of 1-3 wt.% of silver into the nanostructured alloy increased its corrosion rate from 0.24 mm/year to 0.33 and 0.58 mm/year for Fe-30Mn-1Ag and Fe-30Mn-3Ag, respectively. Whilst, the bimodal Fe-30Mn-1Ag alloy corroded at a higher rate of 0.88 mm/year. This alloy also possessed an interesting combination of high and low micro-hardness phases that contributed to high shear strength of 417 MPa and shear strain of 0.66. Detailed discussion on the relationship of microstructure with corrosion behavior and mechanical properties is presented in this manuscript.
