True stress-strain curves of BMG matrix composites with different crystalline volume fractions. The inset shows the microstructures of rods with a diameter of 2 mm and crystalline volume fractions of (a) 5 vol. %, (b) 30 vol. %, and (c) 50 vol. %.
(a) Experimental and calculated values for the fracture strain as a function of the crystalline volume fraction and (b) yield strength vs crystalline volume fraction of the BMG matrix composites.
2D diffraction image of the fully crystalline sample unstressed (left half) and at 1100 MPa. The arrows show the strongest peaks of the new phase , which forms induced by plastic deformation. The inset shows the integrated 2D diffraction images in the undeformed (upper pattern) and deformed (lower pattern) states. Note that the strongest reflection of B2 CuZr has been cut off in the upper diffraction pattern.
Elastic properties of B2 CuZr and the glassy phase in .
