Abstract

Metallic glasses, produced by rapid quenching of metallic melts have emerged as an important class of materials with unusual combinations of desired properties. Further, many of the unique characteristics arise due to their amorphous structure. Study of the amorphous State is of great current interest as evidenced by the publications of books and the proceedings of international conferences on this subject [1–3]. One of the features of these alloys is that they can be prepared with a variety of compositions with a number of elements, providing a method to alter or modify their magnetic, mechanical, electrical, and corrosion behavior. The alloys constitute a large range of material containing from two to as many as five elements. They behave as very soft magnetic materials, exhibit exceptional hardness, high tensile strengths, and almost zero thermal expansion in certain instances. Some of them show marked resistance to corrosion. Such combinations of properties and in particular the existence of ferromagnetism in these alloys, a property earlier thought to be impossible in non-crystalline materials, have made them potential and competitive candidates in a wide range of applications. Recent developments include their suitability in large and electronic-size transformers, in motors, in mechanical applications such as brazing filler materials, as transducers and as potential catalysts.
