Methods for shaping high aspect ratio articles from metallic glass alloys using rapid capacitive discharge and metallic glass feedstock for use in such methods

摘要

The disclosure is directed to a method of forming high-aspect-ratio metallic glass articles that are substantially free of defects and cosmetic flaws by means of rapid capacitive discharge forming. Metallic glass alloys that are stable against crystallization for at least 100 ms at temperatures where the viscosity is in the range of 10⁰ to 10⁴ Pa-s are considered as suitable for forming such high-aspect-ratio articles.
