摘要
The objective of this study is to demonstrate the various artificial features introduced into metallic amorphous alloys by improper TEM sample preparation. Such artifacts are often confused with the intrinsic microstructures when examining metallic glasses under TEM. The electropolishing and ion milling procedures are compared in terms of their merits/drawbacks for avoiding/inducing artifacts in metallic glass samples. (c) 2005 Acta Materialia Inc.
