Journal ArticleDOI
On the microstructure–tensile property correlations in bulk metallic glass matrix composites with crystalline dendrites
R.L. Narayan,Prince S. Singh,Douglas C. Hofmann,Nicholas W. Hutchinson,Katharine M. Flores,Upadrasta Ramamurty +5 more
TL;DR: In this paper, a critical investigation on the microstructure and tensile properties of Zr/Ti-based bulk metallic glass composites of the same composition, but produced by different routes, was conducted so as to identify ''structure-property'' connections in these materials.
Journal ArticleDOI
Tuning the microstructure and metastability of β-Ti for simultaneous enhancement of strength and ductility of Ti-based bulk metallic glass composites
Lili T. Zhang,R.L. Narayan,Huameng Fu,Upradrasta Ramamurty,Li Weirong,Yangde Li,Haifeng Zhang +6 more
TL;DR: In this article, a parametric experimental study on the role played by the size, metastability, and volume fraction of the dendritic β-Ti phase on the tensile properties of amorphous matrix composites is conducted.
Journal ArticleDOI
On the hardness and elastic modulus of bulk metallic glass matrix composites
TL;DR: In this article, the influence of amorphous matrix and crystalline dendrite phases on the hardness and elastic moduli of Zr/Ti-based bulk metallic glass matrix composites have been assessed.
Journal ArticleDOI
Wallner lines, crack velocity and mechanisms of crack nucleation and growth in a brittle bulk metallic glass
TL;DR: In this paper, the authors conclude that the crack initiation in brittle bulk metallic glass (BMG) is stress-controlled and occurs through hydrostatic stress-assisted cavity nucleation ahead of the notch tip.
Journal ArticleDOI
Fracture in metallic glasses: mechanics and mechanisms
TL;DR: In this paper, the authors reviewed and identified the outstanding issues in the context of fracture of amorphous alloys that need to be resolved and established the governing fracture criteria for ductile and brittle glasses.
