“…Similarly, the calculations were performed for the ultimate tensile strength (UTS) values. The values of flow stress at a specific strain [ 33 ] and especially UTS [ 34,35 ] might conform to the Hall–Petch relationship over the whole range of grain size. Using the UTS formula of

{UTS}_{γ} = 565.8 + 191 / \sqrt{D_{γ}}

for AISI 316 stainless steel, the following equation was obtained

UTS = {565.8 + 191 / \sqrt{D_{γ}}} f_{γ} + {600.73 + 821.94 / \sqrt{D_{α}}} f_{α}

“…The main issue that limits the clinical application of Mg-based alloy is its rapid degradation rate, which results in a premature loss of mechanical integrity. Many methods, including thermal deformation, heat treatment, and surface modification, have currently been adopted to improve the corrosion resistance of Mg alloys [133][134][135]. However, further research into the cytocompatibility, osteogenic properties, antibacterial performance, and wound healing effect of these coatings is required.…”

Utilizing biodegradable alloys as guided bone regeneration (GBR) membrane: Feasibility and challenges

Guided bone regeneration (GBR) is a therapeutic procedure used to enhance alveolar bone volume before dental implants. Commercial non-absorbable membranes (i.e., titanium membranes) typically require a second surgery to remove, whereas absorbable membranes (i.e., collagen membranes) will fail when put over extensive bone lesions due to their low mechanical strength. The GBR membrane that has been sought is still being developed. Biodegradable metals (BMs), particularly Mg and Zn, have recently been postulated as promising barrier membrane candidates. Herein, the goal of this research is to evaluate the mechanical and biological feasibility of using BMs as GBR membranes. It shows that BMs have a wide range of potential applications as GBR membranes, owing to their benign biocompatibility, sufficient mechanical support, tunable degradation rate, good osteogenic capabilities, broad-spectrum antibacterial behavior, and improved wound healing ability. The rapid degradation rate, hydrogen evolution impact, and stress corrosion cracking behavior all pose obstacles to the use of Mg-based membranes, which can be improved by surface modifications, heat treatment, alloying, etc. Due to its acceptable degradation rate and lack of gas production, Zn appears to be a better candidate for usage as a GBR membrane. In general, advances in the development of BMs have paved the door for BMs to be used as GBR membranes in oral clinical trials.

“…JMatPro software is used for thermodynamic investigations. [51,52] Figure 10d,e shows the distribution of Cr and Mo elements in carbide, ferrite, and austenite phases, obtained from JMatPro software. The results show that Cr and Mo elements are more dissolved in the carbide phase than the ferrite and austenite phases due to higher carbide's curve.…”

A high strength low alloy (HSLA)‐100 steel with different initial microstructures (ferrite and martensite) is processed by cold rolling at room temperature to the reduction of thickness about 70%. It is found that the recrystallization kinetics of the sample with a martensitic microstructure is higher than the sample with a ferritic microstructure. Moreover, the results show that the partitioning factor of substitution alloying elements is less effective than the strain in the martensitic phase transformation. Also, hardness results show that the samples with a martensitic microstructure have drastic drop compared with the samples with a ferritic microstructure, which is related to continuous recrystallization. Remarkable ultimate tensile strength and elongation to failure (829 MPa and 27.7%, respectively) are achieved for cold‐rolled martensite after tempering at 625 °C for 360 min. Accordingly, it is also found that the reason for remarkable mechanical properties is the simultaneous presence of recrystallized fine‐grained and deformed martensite, which forms an inhomogeneous microstructure.
