| Abstract Scope |
Small scale mechanical behavior of several metallic glasses and their composites were evaluated for fundamental understanding of mechanical response at microstructural length-scales including micro/nano-pillar compression, fatigue, creep and fracture toughness. The creep response was evaluated as a function of loading rate and peak load and will be discussed in the context of shear transformation zones. Strain rate sensitivity was evaluated by micro/nano-pillar compression at different strain rates. Metallic glass composites have a unique microstructure consisting of crystalline dendrites in an amorphous matrix, which leads to distinct crack deflection mechanisms. Site-specific deformation behavior of some of these alloys was studied and phase-specific stress-strain response was evaluated for mechanistic understanding of the bulk response and toughening in these alloys. |
