DESIGN STRATEGIES TO IMPROVE THE PLASTICITY OF BULK METALLIC GLASSES

Qiang Zheng

Abstract

Bulk metallic glasses (BMGs) have many excellent properties, such as high strength, high hardness, high specific strength, better corrosion resistance, and excellent soft magnetic property as well. However, their lack of plasticity due to the shear localization at room temperature which has been considered the Achilles' heel seriously restricts their application as structural materials. So far, a great deal of efforts has been devoted to improving the ductility and toughness of BMGs. In this paper, the-state-of-art eight successful design strategies were summarized in order to give clues and directions to improve the ductility and toughness of bulk metallic glass. Both the advantage and disadvantage of each method were briefly analyzed.
