Abstract:

Bulk amorphous metals are attractive materials for several reasons. An absence of microstructural features such as crystal plains, dislocations, grain and phase boundaries contribute to appealing mechanical properties such as high hardness and high specific strength. The amorphous structure also results in attractive magnetic properties such as high magnetic permeability. Corrosion studies have also established amorphous metals as a group of materials with corrosion properties much more desirable than their crystalline counterparts. As a result, metallic glasses have found their way into common applications including golf club heads, magnetic security strips, step-down transformers and cell phone cases. Within the last 15 years, many successful steps have been made in both understanding the properties of amorphous metals and in processing bulk quantities efficiently. Calcium based bulk metallic glasses constitute a new class of amorphous materials.
