oai:localhost:PNK-94622023-10-05T01:57:22Z Advancing Bulk Metallic Glass Formation: Utilizing Rare-Earth Elements in Zr-Based Alloys Pajor, Krzysztof Gondek, Łukasz Tyrała, Dorota XRD DTA Cc-BY Zr-based bulk metallic glasses (BMGs) are characterized by excellent glass-forming ability, combined with superior mechanical properties. However, oxygen impurities degrade both these aspects as oxides serve as heterogeneous nucleation sites during solidification. Rare-earth elements (REEs) are known to be good oxygen scavengers, binding oxygen to less harmful forms. The most stable rare-earth oxide (REO) is M2O3, which occurs in three polymorphic forms, depending on the radius of metal cation: cubic, hexagonal, and monoclinic. Here, we show the effect of Sc, Y, Lu, Nd, and Gd additions in relation to the oxygen content on the glass-forming ability of the Zr52.5Cu17.9Ni14.6Al10Ti5 alloy. Microscopic observations (SEM) supported by chemical analysis (EDS, WDS), structure identification (XRD), and thermal analysis (DTA) were carried out. 2023-10-05T01:57:22Z 2023-10-05T01:57:22Z 2023 Book https://link.springer.com/article/10.1007/s11661-023-07176-9 https://dlib.phenikaa-uni.edu.vn/handle/PNK/9462 en application/pdf Springer |
