“…In the case of Mn-4Zn-0.2Ca, the corrosion rates were reported to range between (2.43 ÷ 2.67) × 10 −4 A/cm 2 compared to the pure magnesium that is 3.71 × 10 −4 A/cm 2 [ 96 ]. In vitro and in vivo studies reported a 35 ÷ 38% degradation rate that took place in the first 3 months [ 97 ]. Excellent corrosion resistance is present in the case of Mg-Zn-RE alloys such as Mg-Zn-Gd and Mg-Zn-Y.…”

Magnesium (Mg)-based alloys have become an important category of materials that is attracting more and more attention due to their high potential use as orthopedic temporary implants. These alloys are a viable alternative to nondegradable metals implants in orthopedics. In this paper, a detailed overview covering alloy development and manufacturing techniques is described. Further, important attributes for Mg-based alloys involved in orthopedic implants fabrication, physiological and toxicological effects of each alloying element, mechanical properties, osteogenesis, and angiogenesis of Mg are presented. A section detailing the main biocompatible Mg-based alloys, with examples of mechanical properties, degradation behavior, and cytotoxicity tests related to in vitro experiments, is also provided. Special attention is given to animal testing, and the clinical translation is also reviewed, focusing on the main clinical cases that were conducted under human use approval.

“…Studies have indicated that Mg-Zn alloys possess great mechanical properties, biocompatibility, and higher corrosion resistance [141]. Apart from that, the addition of Zn to Mg alloys can significantly reduce H 2 evolution [142,143]. However, depending on the Zn content in binary Mg-Zn alloys and the phase distribution, the corrosion resistance of Mg-Zn alloys extensively differs.…”

In recent decades, we have witnessed radical changes in the use of permanent biomaterials. The intrinsic ability of magnesium (Mg) and its alloys to degrade without releasing toxic degradation products has led to a vast range of applications in the biomedical field, including cardiovascular stents, musculoskeletal, and orthopedic applications. With the use of biodegradable Mg biomaterials, patients would not suffer second surgery and surgical pain anymore. Be that as it may, the main drawbacks of these biomaterials are the high corrosion rate and unexpected degradation in physiological environments. Since biodegradable Mg-based implants are expected to show controllable degradation and match the requirements of specific applications, various techniques, such as designing a magnesium alloy and modifying the surface characteristics, are employed to tailor the degradation rate. In this paper, some fundamentals and particular aspects of magnesium degradation in physiological environments are summarized, and approaches to control the degradation behavior of Mg-based biomaterials are presented.

“…At this point, directed welding lines have been identified; after that, the welding and fracture mechanisms have reached equilibrium, and spontaneously aligned welding lines dominate particle development. The last stage is defined by a steady-state phase wherein the microstructure refining occurs but particle distribution and sizes keep generally constant [88][89][90]. The MA technique is depicted in its totality in figure 5.…”

High entropy alloys (HEAs) earned the attention of the scientific community since their discovery in the year 2004, while the progress in this field has been realized since the year 2010 when a drastic increase in demand for HEAs was observed due to their unique characteristics and ability to form several compositions. As universally acknowledged, the immense potential in compositions, microstructures, and properties has sparked a great interest in this field. Researchers primarily focused on equiatomic HEAs, but the paradigm eventually shifted to non-equiatomic alloys. As the research progressed, four core effects were identified as the most important aspects in enabling the distinct characteristics. Mechanical alloying (MA), followed by the sintering approach, has piqued the interest of all researchers focusing on HEA processing. Accordingly, the main objective of this review is to critically discuss mechanically alloyed HEAs in the view of mechanical properties, tribological behavior, and functional properties. Furthermore, the predominant challenges and their conceivable prospects are also deliberated that offer novelty to this review article.
