Abstract
The amorphous-to-crystalline transformations has been studied extensively since the discovery of glassy alloys. Many physical and chemical properties vary drastically in the course of thermal treatments leading to crystallization, and this seems to be a limit to the applications of these materials. Nevertheless, the intermediate metastable crystallization products, in some cases, or the final crystalline phases show, in several cases, interesting properties. Among the very large number of amorphous systems up to now investigated, Metglas 2826 and 2826A (from Allied Chemical) have received particular attention, because of their magnetic and anticorrosive properties. In the present paper the authors discuss some results on amorphous alloys having compositions similar to the commercial ones and, in particular, they discuss the influence of phosphorus and chromium content on the electrical resistivity variations during thermal treatments up to crystallization.
