Abstract

We employ an electron phase retrieval technique in the transmission electron microscope to reconstruct the projected thickness maps of metallic glass specimens and measure the void distribution at a microscopic level. We examine an as-spun melt-spun Zr66.7Cu33.3 glass and the shear bands formed in this glass from inhomogeneous deformation in tension and compression. Both as-spun and deformed glasses show no variation in projected thickness indicative of voids down to the limit of this medium-resolution technique (0.32nm). This demonstrates that the free volume generated in deformation does not condense into stable voids larger than 0.32nm in radius, but is distributed diffusely in shear bands.
