bulk metallic glass matrix under ultrasonic vibration

forming sandwich-structured bulk metallic glass composites. The interface characterization between matrix and frame reveals a typical metallurgical bonding. By tuning the geometry of Ti6Al4V frame

the composites manifest an enhanced fracture toughness of 213 MPa m

2.3 times higher than that of the monolithic bulk metallic glass. Our findings provide a promising route for the development of metallic composites.

Highlights

Our findings providing a promising route for the fabrication of strong-and-tough BMG composites.Metallurgical bonding was achieved at the interface between BMG matrix and the Ti6Al4V frame.By tuning the geometry of Ti6Al4V frame

the BMG composites exhibited high fracture toughness of about 213 MPa m

1/2

and a bending strength of about 1 GPa.
