“…Bulk metallic glasses (BMGs), as promising structural and functional materials, have been successfully attracting widely attention over the past several years due to their excellent corrosion resistance and unique mechanical properties [1][2][3]. More recently, intensive efforts have been made for fabrication of rare-earth (RE) based BMGs because of their significance in science and commercial application [4][5][6] with their excellent glass-forming ability (GFA), thermal stability and mechanical strength.…”

Gd 55 Al 25 Cu 10 Co 10 bulk metallic glass (BMG) was prepared by copper mold blow casting method with different superheat temperatures. Polarization tests, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) measurements were used to study the influence of superheat treatment on corrosion resistance of Gd 55 Al 25 Cu 10 Co 10 in 3.5% NaCl solution at room temperature. The potentiodynamic polarization analysis shows that the corrosion resistance ability of Gd-based BMG after superheat treatment at different superheat temperatures ranks: 1105℃>1214℃>1066℃>919℃, which agrees well with that of EIS data. In addition, the SEM results reveal that the corrosion products gradually become more uniform for Gd-based BMG at higher superheat temperature and exhibits the best at 1105℃, which shows better corrosion resistance ability. Also, it is interesting that there exists no corrosion pits for all Gd-based BMG. The EDS and XPS results reveal that corrosion resistance has a positive relation with highly corrosion-resistance oxides of corrosion products. It is also found that corrosion resistance ability is in accordance with glass-forming ability (GFA). All these results are considered to be related to the more uniform and homogeneous microstructure after superheat treatment with the increasing superheat temperature.

“…Since the first preparation of La-based bulk metallic glass (BMG) by copper mold casting in 1989 [1], a number of rare earth metal-based BMGs with high glass-forming ability (GFA) and unique thermal and physical properties have been developed for the scientific and engineering significance [2][3][4][5][6]. The main components of the La-based BMGs reported up to date can be formulated by La-(Ce-)Al-TM, in which TM represents transition metals Ni, Cu, Co and Ag [7][8][9][10].…”
