“…In addition to oxidation, the corrosion properties of the Pd, Fe and Cu based BMGs were also studied in Taiwan [83][84][85][86]. They evaluated the corrosion properties of these alloys in various aqueous solutions such as NaCl, HNO 3 , H 2 SO 4 , and HCl.…”

“…In fact, many metallic glasses exhibit different corrosion resistance or etching selectivity in certain states. Some Fe-based and Cu-based bulk metallic glass (BMG) alloys have been found to exhibit better corrosion properties in the amorphous state than that in the crystalline state343536. In other cases, the corrosion resistance of some Pd-based and Fe-based BMGs amorphous alloys can be improved by annealing373839.…”

Currently, the most widely used photoresists in optical lithography are organic-based resists. The major limitations of such resists include the photon accumulation severely affects the quality of photolithography patterns and the size of the pattern is constrained by the diffraction limit. Phase-change lithography, which uses semiconductor-based resists such as chalcogenide Ge2Sb2Te5 films, was developed to overcome these limitations. Here, instead of chalcogenide, we propose a metallic resist composed of Mg58Cu29Y13 alloy films, which exhibits a considerable difference in etching rate between amorphous and crystalline states. Furthermore, the heat distribution in Mg58Cu29Y13 thin film is better and can be more easily controlled than that in Ge2Sb2Te5 during exposure. We succeeded in fabricating both continuous and discrete patterns on Mg58Cu29Y13 thin films via laser irradiation and wet etching. Our results demonstrate that a metallic resist of Mg58Cu29Y13 is suitable for phase change lithography, and this type of resist has potential due to its outstanding characteristics.

“…These accomplishments open new doors to the investigation of other metallic systems, such as Cu-based metallic glasses. These alloy systems are promising candidates for the AM process due to their high GFA, high tensile strength and elongation, and relative low cost of elements [18][19][20][21][22]. Although their high GFA permits achieving critical casting thickness above 20 mm by copper mold injection casting [23,24], they are restricted to simple geometries and specific alloying compositions, which limit the vast usage of Cu-based BMGs in industrial applications as engineering materials when produced by casting.…”

Recently, laser additive manufacturing (AM) techniques have emerged as a promising alternative for the synthesis of bulk metallic glasses (BMGs) with massively increased freedom in part size and geometry, thus extending their economic applicability of this material class. Nevertheless, porosity, compositional inhomogeneity, and crystallization display themselves to be the emerging challenges for this processing route. The impact of these “defects” on the surface reactivity and susceptibility to corrosion was seldom investigated but is critical for the further development of 3D-printed BMGs. This work compares the surface reactivity of cast and additively manufactured (via laser powder bed fusion—LPBF) Cu47Ti33Zr11Ni6Sn2Si1 metallic glass after 21 days of immersion in a corrosive HCl solution. The cast material presents lower oxygen content, homogeneous chemical distribution of the main elements, and the surface remains unaffected after the corrosion experimentation based on vertical scanning interferometry (VSI) investigation. On the contrary, the LPBF material presents a considerably higher reactivity seen through crack propagations on the surface. It exhibits higher oxygen content, heterogeneous chemical distribution, and presence of defects (porosity and cracks) generated during the manufacturing process.
