Metallic glasses, first discovered a half century ago, are currently among the most studied metallic materials. Available in sizes up to several centimeters, with many novel, applicable properties, metallic glasses have also been the focus of research advancing the understanding of liquids and of glasses in general.
Metallic Glasses (MGs) , called also bulk metallic glasses (BMGs) ( or glassy metals , amorphous metals , liquid metals) are considered to be the materials of the future. Due to their high strength, metallic glasses have a number of interesting applications, for example as coatings. Metallic glasses can also be corrosion resistant. Metallic glasses, and the crystalline materials derived from them, can have very good resistance to sliding and abrasive wear. Combined with their strength – and now, toughness – this makes them ideal candidates for bio-implants or military applications. Prestigious Journals such as „Nature Materials”, „Nature” frequently publish new findings on these unusual glass materials. Moreover Chinese and Asian scientists have also been showing an interest in the study of metallic glasses.
This review paper is far from exhaustive , but tries to cover the areas of interest as it follows : a short history , the local structure of BMGs and the glass forming ability ( GFA) , BMGs’ properties , the manufacturing and some applications of BMGs and finally , about the future of BMGs as valuable materials .
