“…As pointed out by several works, the evolution of pores is inevitable during LPBF [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. It can arise during the powder deposition, from hollow powder particles and from the laser power distribution [ 8 ].…”

The constraint in sample size imposed by the critical cooling rate necessary for glass formation using conventional casting techniques is possibly the most critical limitation for the extensive use of bulk metallic glasses (BMGs) in structural applications. This drawback has been recently overcome by processing glass-forming systems via additive manufacturing, finally enabling the synthesis of BMGs with no size limitation. Although processing by additive manufacturing allows fabricating BMG objects with virtually no shape limitation, thermoplastic forming of additively manufactured BMGs may be necessary for materials optimization. Thermoplastic forming of BMGs is carried out above the glass transition temperature, where these materials behave as highly viscous liquids; the analysis of the viscosity is thus of primary importance. In this work, the temperature dependence of viscosity of the Zr52.5Cu17.9Ni14.6Al10Ti5 metallic glass fabricated by casting and laser powder bed fusion (LPBF) is investigated. We observed minor differences in the viscous flow of the specimens fabricated by the different techniques that can be ascribed to the higher porosity of the LPBF metallic glass. Nevertheless, the present results reveal a similar overall variation of viscosity in the cast and LPBF materials, which offers the opportunity to shape additively manufactured BMGs using already developed thermoplastic forming techniques.

“…During LPBF processing, Zr-based glass-forming alloys are enriched in oxygen so that the resulting BMGs show a distinctly lower fracture toughness than cast BMGs [ 5 , 15 , 16 ]. By contrast, their wear and corrosion resistances are similar [ 8 , 17 ].…”

“…The first attempt to used SLM to fabricate fully amorphous BMG components under the appropriate conditions was carried out by Pauly et al [388] in 2013. Since then, several other BMGs based on Fe [388][389][390][391][392][393][394][395][396], Al [397][398][399][400], Zr [401][402][403][404][405][406][407][408][409][410][411][412][413][414], Cu [415,416], Pd [417], and Ti [418] have been fabricated using the laser PBF process. A sample made of Fe-based BMGs as large as 45 mm in diameter and 20 mm in length was fabricated by Wang et al [419].…”

Additive manufacturing (AM) as a disruptive technology has received much attention in recent years. In practice, however, much effort is focused on the AM of polymers. It is comparatively more expensive and more challenging to additively manufacture metallic parts due to their high temperature, the cost of producing powders, and capital outlays for metal additive manufacturing equipment. The main technology currently used by numerous companies in the aerospace and biomedical sectors to fabricate metallic parts is powder bed technology, in which either electron or laser beams are used to melt and fuse the powder particles line by line to make a three-dimensional part. Since this technology is new and also sought by manufacturers, many scientific questions have arisen that need to be answered. This manuscript gives an introduction to the technology and common materials and applications. Furthermore, the microstructure and quality of parts made using powder bed technology for several materials that are commonly fabricated using this technology are reviewed and the effects of several process parameters investigated in the literature are examined. New advances in fabricating highly conductive metals such as copper and aluminum are discussed and potential for future improvements is explored.

“…This is caused by the creation of micro-galvanic sites with the addition of Mn which creates a biphasic composition of γ and ɛ phases [95]. Zr-based bulk metallic glasses (BMG) fabricated by SLM is another topic of a recent study for biomedical applications [65,96]. The corrosion resistance of this SLM Zr-based BMG was higher than cast Zr-based BMG and Ti-6A-l4V in simulated body fluid in terms of both corrosion rate and passive current density.…”

Products made from additive manufacturing processes have attracted great attention in engineering, health care, and society at large. However, there is little knowledge about the failure of additively manufactured alloys, in particular, corrosion and wear seen in most engineering applications. The haphazard and inefficient usage of such alloys raised concerns about safety, compatibility, reliability, cost, and consumer satisfaction. To address those concerns, we studied the mechanisms of the most common failure modes, corrosion and wear, of alloys fabricated through additive manufacturing based on published literature. It was found that the processing conditions have profound influence on microstructure and thus corrosion and wear resistance of alloys. Because of the layered structure, the initiation and growth of both corrosion and wear exhibited anisotropic behavior. The insights from this review could be used as a reference of the state-of-the art and to help in the development of future additively manufactured alloys with improved corrosion and wear properties.
