Figure 3. (A) Ashby map of fracture toughness versus density of materials including the location of select bulk metallic glasses and Zr-Ti-Nb-Cu-Be bulk metallic glass matrix composites; Composite alloys have among the highest fracture toughness (B) Ashby map of fracture toughness versus yield strength of materials including selected metallic glasses and composites. Contour lines indicate plastic zone size, and the shaded region signifies the diameter (d) < 1 mm region that typically confines monolithic metallic glasses.  The plastic zone size of the toughened composites is shown in the inset.
