“…In addition to reducing the roughness in the AM process, post-treatment steps, such as those involving the formation of a coating or oxide on the surface, are generally not required. At present, the research trend of amorphous alloy SLM manufacturing is that on the one hand, the development of new materials is in progress, and on the other hand, the research results of material forming in the early stage have promoted the continuous development of new structures, such as the honeycomb structure [137] and metal frame reinforced BMG composites [31]. The composite material greatly improves the specific strength, quasi-plasticity, and elastic elongation of the metallic glass SLM structure.…”

“…The bulk metallic glass prepared by this method has the potential for engineering applications [29,30]. Inspired by the seismic structure of skyscrapers, Li designed a tubular structure of Ti 6 Al 4 V frame [31]. Under ultrasonic vibration, Zr 35 Ti 30 Be 26.75 Cu 8.25 was used for 3D printing and thermoplastic molding with a large metal glass matrix to form a sandwich structure of large metal glass composite material.…”

Bulk metallic glasses (BMGs) are a subject of interest due to their superior specific properties such as low coefficient of friction, high strength, large ductility in bending, high elastic modulus, high microhardness, and high resistance to corrosion, oxidation, wear, and so on. However, BMGs are difficult to apply in industry due to their difficulty in manufacturing and secondary operation. In the past few decades, many efforts have been carried out to overcome the defects in the manufacturing of BMGs. It is difficult to fabricate complex structures with the whole amorphous alloy owing to the limit of crystallization and critical cooling rate. Additive manufacturing (AM), such as selective laser melting (SLM), can obtain relatively high cooling rates during the “layer-by-layer” process, which makes it possible to surpass the dimensional limitation of metallic glass. In the SLM process, the high-speed cooling of molten pool and the avoidance of secondary processing are very beneficial to the production and application of amorphous alloys. In this paper, based on the research of SLM additive manufacturing BMGs in recent years, the factors affecting crystallization and forming ability are discussed from many aspects according to different material systems. The status and challenges of SLM manufacturing BMGs including Fe-based, Zr-based, Al-based, and some composite-based BMGs will be presented. Mechanical properties and physicochemical properties were introduced. This review aims to introduce the latest developments in SLM additive manufacturing BMGs, especially on the development of process parameters, structure formation, simulation calculation, fracture mechanism, and crystallization behavior. With the traditional fabricating methods, BMGs were mainly used as a structure material. It will provide another alternative to use BMGs as a functional material by introducing SLM technology in amorphous preparation with complex geometry. This review summarizes the technical difficulty and application prospects of BMGs preparation by SLM and discusses the challenges and unresolved problems. This review identifies key issues that need to be addressed in this important field in the future. These problems are related to the application of BMGs as high-strength structural materials and new functional materials in the future.

“…The development of expanded areas of application requires the possibility of joining with materials of the same type and, in particular, with crystalline materials, including light alloys such as aluminum [ 3 , 4 ]. In addition to the direct manufacture of a product, the production of semi-finished products is also possible, for example composite materials in sandwich construction with a crystalline core and metallic glasses as cover layers [ 8 ]. A suitable joining technique must ensure that, in addition to high joint strength, the amorphous structure of the metallic glasses and thus their special properties are retained [ 7 ].…”

Ultrasonic metal welding (UMW) enables joining in the solid state at relative low temperatures with short cycle times. This technique is of particular interest for joining metallic glasses to each other or to other materials, because crystallization of the amorphous structure can be prevented due to the low thermal loading and the rapidity of the process. In this work, UMW is applied to join one 1 mm thick sheet of a commercial wrought aluminum alloy (AA5754) and one 0.4 mm thick strip of a commercial Zr-based bulk metallic glass (AMZ4). The introduced heat of the welding process is detected with thermocouples and thermal imaging. To investigate the strength of the joint and the influence on the microstructure, mechanical tensile tests are carried out in combination with scanning electron microscopy and differential scanning calorimetry. The results show that ultrasonic metal welding is a suitable technique to join amorphous bulk metallic glasses to crystalline aluminum alloys. The metallic glass component retains its amorphous structure in the joint, and the joint strength is higher than the strength of the Al sheet. These findings will help to develop future applications of BMG-based multi-material components, including medical tools.

“…Recent years have seen active research in the area of aluminum matrix composites directed at evaluating the suitability of alternative (non-ceramics) reinforcements. In novel composites, particles of intermetallics [2,3], quasicrystals [4], high-entropy alloys [5,6], or metallic glasses [7][8][9][10][11][12][13][14] are used as the reinforcing elements. These composites are usually produced by powder metallurgy via consolidation of mixtures of the matrix metal and metallic alloy powders.…”

“…In most studies dealing with metallic glass-aluminum mixtures, the goal has been to preserve the glassy state of the reinforcement during the formation of the bulk material. Composites have been obtained, in which the layers forming at the metal matrix/metallic glass interface possess very small thicknesses (in the nanometer range) [12,14]. When a particle introduced into a matrix starts chemically interacting with it, a core-shell structure forms upon partial consumption of the particle material.…”

At present, metallic glasses are evaluated as alternative reinforcements for aluminum matrix composites. These composites are produced by powder metallurgy via consolidation of metallic glass-aluminum powder mixtures. In most studies, the goal has been to preserve the glassy state of the reinforcement during consolidation. However, it is also of interest to track the structure evolution of these composites when partial interaction between the matrix and the metallic glass is allowed during sintering of the mixtures. The present work was aimed to study the microstructure and mechanical properties of composites obtained by spark plasma sintering (SPS) of Al-20 vol.% Fe66Cr10Nb5B19 metallic glass mixtures and compare the materials, in which no significant interaction between the matrix and the Fe-based alloy occurred, with those featuring reaction product layers of different thicknesses. Composite materials were consolidated by SPS at 540 and 570 °C. The microstructure and mechanical properties of composites obtained by SPS and SPS followed by forging, composites with layers of interfacial reaction products of different thicknesses, and metallic glass-free sintered aluminum were comparatively analyzed to conclude on the influence of the microstructural features of the composites on their strength.
