“…This can be attributed to the previously-observed narrower pores with lower standard deviations obtained through sintering, resulting in less randomised pores with 18 min microwave sintering showing the most pronounced effect, as well as the material’s porosity having lower standard deviation. The sintered materials, though inferior in mechanical and/or compressive response are also closer to those of human cancellous bone in terms of mechanical properties, which is a beneficial characteristic as it minimises stress-shielding of bones as they heal [ 53 , 54 ].…”

A new and novel method of synthesising porous Mg materials has been explored utilising a variant of a processing method previously used for the synthesis of dense Mg materials, namely the turning-induced deformation (TID) method combined with sintering. It was found that the Mg materials synthesised possessed comparable properties to previously-synthesised porous Mg materials in the literature while subsequent sintering resulted in a more consistent mechanical response, with microwave sintering showing the most promise. The materials were also found to possess mechanical response within the range of the human cancellous bone, and when reinforced with biocompatible silica nanoparticles, presented the most optimal combination of mechanical properties for potential use as biodegradable implants due to most similarity with cancellous bone properties.

“…210,211 Any variation in the moduli of neighbouring porous units will also significantly affect the transmission of loads in the case of gradient porous scaffolds. 212 Therefore, it is suggested to maintain smooth continuity among neighbouring porous units having different moduli. This can be achieved by maintaining uniform strut dimensions across the structures.…”

“…This can be achieved by maintaining uniform strut dimensions across the structures. 212 However, all these structures lack sufficient mechanical strength, especially in case of polymeric scaffolds. In this regard, various studies have been carried out in the past to establish the relationship between the geometric and mechanical behaviour of high-performance structures found in nature.…”

“…[8], with materials such as steel and titanium having widespread use [9]. In this field, a different set of challenges presents itself, ranging from the need to match the property of human bone as closely as possible to avoid stress-shielding [10], minimizing the typically high corrosion rates in the human body environment [11], and overcoming concerns regarding toxicity or lack of biological incompatibility of the very materials used as implants or fasteners in the case of steels (via their alloying elements, e.g., nickel and chromium) [12]. As a metal which is not only biocompatible with, but also potentially bioresorbable within, the human body [13,14], magnesium is potentially well suited for such applications.…”

In this study, the Mg-15Se binary system was, for the first time, investigated and synthesized using the powder metallurgy (PM) method, including microwave sintering and hot extrusion. The resulting material was shown to possess visible pores with a porosity of 2.91%, higher than other Mg materials synthesized using this method in the literature. Despite this, the material not only exhibited a comparable corrosion response with pure Mg but also a significantly superior mechanical response (76% greater damping capacity, 57% increase in hardness, and increases of 21%, 50%, and 51% for compressive yield strength, ultimate compressive strength, and fracture strain, respectively). Thus, this not only opens the door for future work concerning the addition of medicinal Se to nutritional Mg element and the optimization of process parameters but also could potentially be making inroads into the biomedical field with the use of selenium as a biomedical-oriented alloying element.
