“…[39,79] First they found that as the cycling numbers increase, the nanostructure can be modified from smooth nanorods into branched dendritic nanostructures. As shown in Figure 10, [78] the dendritic nanostructure only occurs when the potential goes beyond EC2. We note however, that it is not the general case that longer cycles of dealloying will lead to this specific dendritic nanostructure.…”

“…Besides, it is reasonable to expect that this carbothermal shock (CTS) method can be used to fabricate MGNs if higher cooling rates can be achieved (Figure 9d). [77] Schroers et al [78] recently demonstrated the capability for 3D printing metals using methodologies similar to those for thermoplastic, which might shed light upon on the community that future developments may yield the ability to 3D print MGNs.…”

transformers [2] and load bearing applications. [3] In the last few decades, the study of nanomaterials has become a central focus in nanoscience and nanotechnology. [4] In fact, many studies have shown that with reduction in size, nanomaterials display novel electrical, mechanical, chemical and optical properties, which are largely believed to be the result of surface and quantum confinement effects. [4,5] Remarkably, this trend has found traction in the metallic glass field where metallic glasses nanostructures (MGNs) demonstrate an important role in many applications such as light harvesting, [6] photovoltaic, [7] biomedical, [8] magneto-optical, [9] organic synthesis, [10] lithium-ion batteries [11] and electrocatalysis. [12] Recently, MGNs are receiving increased attention due to their distinguished performance, such as high activity and long term stability in electrocatalytic reactions. [12,13] Although several review papers have already covered the topic of nanopatterning of bulk metallic glasses (BMGs), [14][15][16] the correlation between recent synthetic methods and electrocatalytic applications for MGNs has not been thoroughly addressed. Moreover, there is currently no review that unites MGNs synthesized from different approaches (top-down and bottom-up) with conventional electrochemical reactions. Therefore, in this review our mission is to: 1) present a focused perspective on the latest fabrication techniques of MGNs toward the pursuit of novel electrocatalysts and electrodes; 2) highlight recent advances in computational screening and predictions that could be applied toward new metallic glass electrocatalyst discovery; and 3) report distinct advancements in electrocatalytic applications related to MGNs by creating a comprehensive discussion for commonly employed kinetic parameters and their connection with the unique material structure. Finally, as the first progress report on the metallic glass based electrocatalysts, we will also highlight some of the challenges that need to be addressed toward future progress in this field.BMGs are those metallic glasses (MGs) that can be made in 'bulk' scale with good glass forming abilities, [17] representing a versatile platform for many applications. To date, a wide range of BMG-forming alloys have been developed, including Zr-, [18] Fe-, [19] Cu-, [20] Ni-, [21] Ti-, [22] Mg-, [23] Pd-, [24] Au-, [25] and Pt-based compositions. [26] Moreover, the increased disorder brought by the higher degree of multinary systems is believed to contribute to improving the glass formation. [27] The evolution to multicomponent alloys of the most recent MG studies has also made them natural candidates for catalysis. The amorphous multinary Recent advances in metallic glass nanostructures (MGNs) are reported, covering a wide array of synthesis strategies, computational discovery, and design solutions that provide insight into distinct electrocatalytic applications. A brief introduction to the development and unique features of MGNs with an overview of top-down and bottom-up sy...

“…Recent approaches aim at printing binder-free metals. Kim et al [93] developed a volumetric metal 3D printing system that can dissolve and eject binder-free molten Sn40Pb alloy materials. Another approach, which can be classified as filament-based extrusion, is by utilizing bulk metallic glasses (BMG) that show high mechanical properties.…”

Beamless Metal Additive Manufacturing

2020

The propensity to manufacture functional and geometrically sophisticated parts from a wide range of metals provides the metal additive manufacturing (AM) processes superior advantages over traditional methods. The field of metal AM is currently dominated by beam-based technologies such as selective laser sintering (SLM) or electron beam melting (EBM) which have some limitations such as high production cost, residual stress and anisotropic mechanical properties induced by melting of metal powders followed by rapid solidification. So, there exist a significant gap between industrial production requirements and the qualities offered by well-established beam-based AM technologies. Therefore, beamless metal AM techniques (known as non-beam metal AM) have gained increasing attention in recent years as they have been found to be able to fill the gap and bring new possibilities. There exist a number of beamless processes with distinctively various characteristics that are either under development or already available on the market. Since this is a very promising field and there is currently no high-quality review on this topic yet, this paper aims to review the key beamless processes and their latest developments.

“…1 shows the mutual influence of different technologies and blurring the boundaries between them (Williams, B., 2018). (Petzoldt, 2018) Of the entire variety of ATs, there are only two technologies that are directly related to the materials used in the MIM technology -this is the technology for the production of molten filament (Fused Filament Fabrication -FFF) (Wu et al, 2002;Wolff et al, 2019;Gibson et al, 2018), and jet binder application (BinderJet) (Williams, N., 2018;Dizon et al, 2018;Ngo et al, 2018). With FFF technology, a metal powder mixture (feedstock) is directly used for MIM technology, and in BinderJet technology, powder and binder are used separately (Williams, N., 2018;Digital Metal, 2019;ExOne, 2016ExOne, , 2018BASF, 2018).…”

The paper is concerned with the cost reduction of the elements' production according to the metal injection molding technology of metal powder mixtures (MIM), using the additive technologies (AT) for the production of the green part. This method allows obtaining high fidelity of the materials both in mass production and in one of a kind, and small-series production because it is not necessary to the production of expensive casting press mold of metal powder mixture on the injection molding machine. In his paper, the author showed the advantages and disadvantages of two AT technologies which directly use materials for MIM technology: the technology of fused filament fabrication (Fused Filament Fabrication-FFF) and the technology of Binder Jet (BJ). The author proposes to reduce costs reduction of manufacturing filament for 3D printing according to the FFF technology of green part using already existing feedstock as the basis. The manufacturing technology of the filament is shown by the example of the feedstock steel 316LW BASF. The specific character of the technology is a limited amount of polyoxymethylene (POM) and low-density polyethylene (LDPE) is introduced into the standard composition of the feedstock to increase its plasticity. The author presented the results of tensile testing of items manufactured by standard technology and using AT technologies. Some reduction in the strength characteristics of the items with the using AT technologies is primarily due to the printing modes. The optimization of print modes allows obtaining the properties of the items, not inferior items by standard technology.
