“…Spontaneous crystallization is normally inevitable. It is believed that die casting (10 1 -10 3 K s −1 ), [38] melt spinning (10 5 -10 6 K s −1 ), liquid splat-quenching (10 9 -10 10 K s −1 ), and pulse laser quenching (10 12 -10 13 K s −1 ) [71] cannot satisfy the supercooling requirements for the formation of single element MGs. Zhong et al reported a rapid quenching route with unprecedented high liquid quenching rate (10 14 K s −1 ) to obtain vitrified metallic element.…”

Owing to its unique atomic arrangement and electronic structure, metallic glass (MG) has been widely investigated in the field of energy storage and conversion. In the past few decades, multiple strategies have been developed to synthesize bulk and nanosized MG based materials. Here, combining the structure–activity relationship of MG with electrochemical reaction kinetics, the substantial progress of glass structures in electrocatalytic processes are highlighted, including the hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, methanol oxidation reaction, carbon dioxide reduction reaction, and nitrogen fixation. Meanwhile, applications of MG materials in energy storage devices, like supercapacitors and lithium‐ion batteries, are also introduced in detail. Finally, challenges and possibilities for reasonable design of highly‐efficient MG‐based electrode materials are proposed. The integration of high‐throughput methods, artificial intelligence technology, as well as advanced characterization techniques is fundamental to screen materials with remarkable performance. This review aims to deepen the understanding of the relationship between electronic structure and electrochemical performance, providing guidance for rational design of functional MG materials with outstanding activity, selectivity, and durability.

“…The parameters are different according to the powder composition, particle size, sphericity, and even the difference of equipment. According to most studies, the reasonable energy density is in the range of 30-100 J/mm 3 [50,79,80,[83][84][85][86]. Hofmann studied the effect of processing on the microstructure and properties of an FeCrMoBC glass-forming alloy through a variety of manufacturing parameters by SLM [74].…”

“…In particular, the maximum fracture toughness of BMGCs after mixing with Cu particles reached 47 MPa m 1/2 , which is about 20 times higher than that of Fe-based BMG (2.2 MPa m 1/2 ). Interestingly, Li also used SLM technology to combine an iron-based highentropy alloy with an iron-based glass to produce a composite with both high strength and high toughness [79]. The strength and toughness of the composite can be effectively adjusted with the difference of metal glass content.…”

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.

“…Apart from SPS, SLM is the most widely studied AM technique for HEAs . HEAs that were successfully fabricated by SLM include CoCrFeNiMn [153,154,169,[176][177][178][179][180][181][182][183][184][185]188,[202][203][204][205][206]209,212,214,215,217,220,221], AlCrFeNiV [193], AlCoCrFeNi [170,190], Al-CoCrCuFeNi [194], CoCrFeNi [98,155,186,187,189,208,213,222], CoCr 2.5 FeNi 2 TiW 0.5 [223],…”

“…They have also shown that the properties of HEAs could be altered by changing the input parameters for AM process. For example, CoCrFeNiMn was manufactured with SLM by multiple researchers [153,154,169,[176][177][178][179][180][181][182][183][184][185]188,[202][203][204][205][206]209,212,214,215,217,220,221] and many of them acquired different mechanical properties for CoCrFeNiMn by changing input parameters in AM processes (refer Tables 1-3).…”

Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added to the principal metal. However, a new alloying technique emerged in 2004 with the concept of adding several principal elements in or near equi-atomic concentrations. These are popularly known as high entropy alloys (HEAs) which can have a wide composition range. A vast area of this composition range is still unexplored. The HEAs research community is still trying to identify and characterize the behaviors of these alloys under different scenarios to develop high-performance materials with desired properties and make the next class of advanced materials. Over the years, understanding of the thermodynamics theories, phase stability and manufacturing methods of HEAs has improved. Moreover, HEAs have also shown retention of strength and relevant properties under extreme tribological conditions and radiation. Recent progresses in these fields are surveyed and discussed in this review with a focus on HEAs for use under extreme environments (i.e., wear and irradiation) and their fabrication using additive manufacturing.
