研制了一种用于微纳米金属玻璃纤维制备的过冷液相萃取方法及装置。利用该纤维制备装置，在金属玻璃的过冷液相区通过超塑性变形拉丝，可以获得直径为70 nm ~ 300 μm的微纳米金属玻璃纤维。所获得的金属玻璃纤维具有精确设计和控制的尺寸、高结构均匀性和高表面光滑度。
A supercooled liquid extraction method and apparatus for micro and nanoscale metallic glassy fiber preparation was developed. Using the fiber fabrication equipment, micro to nanoscale metallic glassy fibers with diameter ranging from 70 nm to 300 μm can be obtained by wire drawing in the supercooled liquid region of metallic glasses via superplastic deformation. The obtained metallic glassy fibers possess precisely designed and controlled sizes, high structural uniformity and high degree of surface smoothness.
