| Abstract: | Bulk metallic glasses(BMGs) have many excellent properties,such as high strength,high hardness,high specific strength,corrosion resistance,excellent soft magnetic property and so on.However,their nearly zero plastic strain at room temperature seriously restricts their application as structural materials.So far,a great deal of effort has been devoted to improving the ductility and toughness of BMG.This paper summarizes the recent progress in improving the ductility and toughness of bulk metallic glass and analyzes the advantage and disadvantage of each method. |
