Low Density Ti-based Bulk Metallic Glasses as a
Matrix For High Performance Metallic Glass
CompositePI W.L Johnson
Bulk metallic glass (BMG) matrix composites
exhibiting gt10 tensile ductility and fracture
toughness greater than the toughest metals are
high performance composites, demonstrating
potential of metallic glass as revolutionary
structural metals.
The BMG matrix composites contain elastically
soft dendrites embedded in a glassy matrix.
Toughening and ductility are achieved by a
mechanism similar to the toughening of plastics
by soft inclusions such as rubber.
