在Ar气氛中通过单辊熔融纺丝技术进行铸锭。所述带为约10 mm宽和约40 mm厚。在Ar气氛中以0.67 K/s的加热速率通过X射线衍射（CuK 3，40 kV，40 mA，以下表示为XRD）和差示扫描量热法（DSC）检查熔纺薄带样品的非晶性和热稳定性。由SUS 316L制成的多孔金属盘购自美国Mott Corporation。通过SEM粗略估计具有0.2mm、0.5mm和2 mm筛目尺寸（中等等级）的基底的孔径分别为约15 mm、30 mm和70 mm。圆盘直径为11 mm，厚度为1 mm。此外，在本研究中还使用了世伟洛克公司的多孔过滤器。孔径为约100 mm。将玻璃带切割成宽约5 mm、长约20 mm的样品片。
ingot by the single-roller melt-spinning technique in an Ar atmosphere. The ribbons were about 10 mm wide and about 40 mm thick. Amorphicity and thermal stability of melt-spun ribbon specimens were examined by X-ray diffractometry (CuK� , 40 kV, 40 mA, hereafter denoted as XRD) and differential scanning calorimetry (DSC) at a heating rate of 0.67 K/s in an Ar atmosphere. The porous metallic discs made of SUS316L were purchased from the Mott Corporation, USA. The pore sizes of the substrates having mesh sizes (media grade) of 0.2 mm, 0.5 mm and 2 mm are roughly estimated by SEM to be about 15 mm ,3 0mm and 70 mm, respectively. A disc is of 11 mm in diameter and of 1 mm in thickness. Besides, the porous filter of the Swagelok Co. Ltd. is also used in this study. The pore size is about 100 mm. The glassy ribbons were cut into the sample pieces of about 5 mm in width and about 20 mm in length.
