Abstract

Interfaces between a Ni₅₉Zr₂₀Ti₁₆Si₂Sn₃ bulk metallic glass (BMG) and crystalline brass reinforcements were characterized using transmission electron microscopy and nanoindentation. An interfacial layer with a thickness of ∼50-100 nm was observed in the composite prepared by warm extrusion of gas atomized powders. Microstructural characterization and chemical analysis suggest that the formation of interfacial layer was caused by interdiffusion between the BMG and brass during the warm extrusion. Nanoindentation in the vicinity of BMG-brass interfaces does not cause interface decohesion or crack formation, suggesting a strong interface bonding. Apparently, the resultant interfacial layer not only enhances interfacial bonding but also provides a buffer zone to prevent the catastrophic shear band propagation in the BMG matrix.
