Rate dependence of serrated flow in a metallic glass
Plastic deformation of metallic glasses at low temperatures is known to be highly localized to narrow shear bands. It is generally believed that shear-band formation is very weakly dependent on the strain rate or temperature. However, some reports suggest that the strain rate affects shear-band formation. Mukai et al. reported that the density of shear bands in a Pd-based bulk metallic glass in...
متن کاملRate dependence of serrated flow during nanoindentation of a bulk metallic glass
Plastic deformation of Pd–40Ni–20P bulk metallic glass (BMG) was investigated by instrumented nanoindentation experiments over a broad range of indentation strain rates. At low rates, the load–displacement curves during indentation exhibited numerous serrations or pop-ins, but these serrations became less prominent as the indentation rate was increased. Using the tip velocity during pop-in as a...
متن کاملCooling-rate effects in a model of (ideal?) glass
Using Monte Carlo simulations we study cooling-rate effects in a three-dimensional Ising model with four-spin interactions. During coarsening, this model develops growing energy barriers which at low temperature lead to very slow dynamics. We show that the characteristic zero-temperature length increases very slowly with the inverse cooling rate, similarly to the behaviour of ordinary glasses. ...
متن کاملTuning the Mechanical and Antimicrobial Performance of a Cu-Based Metallic Glass Composite through Cooling Rate Control and Annealing
The influence of cooling rate on the wear and antimicrobial performance of a Cu52Z41Al₇ (at. %) bulk metallic glass (BMG) composite was studied and the results compared to those of the annealed sample (850 °C for 48 h) and to pure copper. The aim of this basic research is to explore the potential use of the material in preventing the spread of infections. The cooling rate is controlled by chang...
متن کاملPressure effects on Ca60Al40 metallic glass superconductors
Theoretical computation of the pressure dependence superconducting state parameters of binary Ca60Al40 is reported using model potential formalism. Explicit expressions have been derived for the volume dependence of the electron–phonon coupling strength λ and the Coulomb pseudopotential μ* considering the variation of Fermi momentum KF and Debye temperature ӨD with volume. Well known Ashcroft’s...
