Bulk Metallic Glasses and Their Composites: A Brief History of Diverging Fields
Figure 7
(a) Ashby map of fracture toughness versus density showing the location of select bulk metallic glasses and Zr-Ti-Nb-Cu-Be bulk metallic glass matrix composites. The composite alloys have among the highest fracture toughness for their density. (b) Ashby map of fracture toughness versus yield strength showing select metallic glasses and composites. Contour lines indicate plastic zone size and the shaded region signifies the mm region that typically confines monolithic metallic glasses. The plastic zone size of the toughened composites is shown in the inset.
