متن کاملSpall strength of a zirconium-based bulk metallic glass under shock-induced compression-and-shear loading
We present results of a series of plate-impact experiments conducted to understand spall threshold in a zirconium-based bulk metallic glass (BMG), Zr41.25Ti13.75Ni10Cu12.5Be22.5, following normal shock-induced compression and combined compression-and-shear loading. The experiments were conducted using a 82.5 mm bore single-stage gas-gun. A multibeam VALYN VISAR was used to measure the particle–...
متن کاملHeterogeneous relaxation dynamics in amorphous materials under cyclic loading.
Molecular dynamics simulations are performed to investigate heterogeneous dynamics in amorphous glassy materials under oscillatory shear strain. We consider three-dimensional binary Lennard-Jones mixture well below the glass transition temperature. The structural relaxation and dynamical heterogeneity are quantified by means of the self-overlap order parameter and the dynamic susceptibility. We...

Crystallization kinetics of Fe52Cr18Mo7B16C4Nb3 alloy was evaluated using X-ray diffraction, differential scanning calorimetric (DSC) tests and TEM observations in this research work. In effect, crystallization and growth mechanisms were investigated using DSC tests in four different heating rates (10, 20, 30, 40 K/min) and kinetic models (i.e. Kissinger- Starink, Ozawa, and Matusita methods). ...
