(a) Idealization of a crystalline dendrite in a BMG composite. is the random orientation angle of the dendrite. (b) Two-point correlation function. (c) Shear stress-strain curves for the BMG composites, Comp1, Comp2, and Comp3, with 30% area faction of the ductile phase.
Representative BMG composite microstructures for (a) Comp1, (b) Comp2, and (c) Comp3. Dark (light) domains represent glassy (ductile) phase. Shear strain contours at 10% nominal strain for (d) Comp1, (e) Comp2, and (f) Comp3. Shear strain contours at 11.5% nominal strain for (g) Comp1, (h) Comp2, and (i) Comp3.
(a) Total strain to failure and (b) ultimate strength for BMG composites as a function of at different values, where is the characteristic length scale associated with the dendritic phase and is the area fraction of the ductile phase.
