Yes,I started working on thin film metallic glasses in late eighties. I found out that the thicker the film of a metallic glass, one wishes to obtain, the more the film is susceptible to a partial crystallization, to lose the amorphous nature. In other words, there is a definite limit of how thick the amorphous film one can obtain. The thickness of the amorphous film is governed by the temperature gradient during the fabrication of the film.
Because it was difficult to develop completely bulk components of amorphous metallic alloys, the name of meta-materials (Functional materials) has came about.
Of course. Take into account that the themodinamically stable form it the crystalline one. After certain amount of deposited material it would @forget@ the influence of the amorphous substrate (I assume you use glass) and assume the more stable configuration. There are lots of models that explain this. try a literature search about.
