In situ dendrite reinforced Bulk Metallic Glass matrix composites (BMGCs) are known to overcome poor ductility and fracture response exhibited by monolithic bulk metallic glasses (BMGs). In this paper (Shear fracture in bulk metallic glass composites) recently published by our group in Acta Materialia, we report mode I and mode II fracture experiments on the above in situ BMGCs containing transforming and non-transforming dendrites. Results show that the fracture initiation toughness of these BMGCs is considerably lower in mode II than in mode I. However, stable crack growth is observed to be considerable in mode II and insignificant in mode I.
