Mechanical properties of bulk metallic glasses

Deformation behavior of the Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass over a wide range of strain-rates and temperatures

The widespread enthusiasm for research on bulk metallic glasses is driven by both a fundamental interest in the structure and properties of disordered materials and their unique promise for structural and functional applications. Unlike the case for crystalline materials, the disordered and nonequilibrium nature of metallic glasses causes their underlying deformation mechanisms to be poorly known. A definite correlation between mechanical behavior and the atomic/electronic structures of metallic glasses has not been established. In this article, I focus on the micromechanisms of mechanical behavior of metallic glasses and present a brief overview of the current understanding of their strength, ductility, and plasticity at the microscopic and atomic scales. The important factors that control the mechanical behavior of metallic glasses are outlined on the basis of recent theoretical and experimental findings. The outstanding issues highlighted in this review are expected to be important for future research ...

Structural disordering in amorphous Pd40Ni40P20 induced by high temperature deformation

Structural relaxation induced by hydrostatic pressure is experimentally observed for the metallic glass ${\mathrm{Pd}}_{40}{\mathrm{Ni}}_{40}{\mathrm{P}}_{20}$. The pressure dependence of the structural state is displayed in the shape of the glass-transition peak that is measured by means of differential scanning calorimetry after annealing treatments at 563 K and pressures up to 0.75 GPa. Quantification of the effect using the free-volume theory yields a formation volume of $5.9\ifmmode\pm\else\textpm\fi{}0.5{\AA{}}^{3}$ for defects in this glass. In combination with the previously determined pressure dependence for the Au diffusivity, a value of $5\ifmmode\pm\else\textpm\fi{}4{\AA{}}^{3}$ is derived for the migration volume for Au diffusion.
