The Transition between Anelasticity and Plasticity in Glass-Forming Metallic Liquids

ثبت نشده
چکیده

6.1 Abstract The relaxation processes of metallic glasses are investigated by observing the changes in material properties associated with the transient stress strain response of specimens subjected to isothermal deformations. The properties studied include the isoconfigurational shear modulus, configurational enthalpy, and the anelastic strain of the material. Conventional glass relaxation processes and Eshelby Stresses are applied to the description of the relaxations observed in the transient response of the material. Additionally, the criteria for shear localization and the barrier height controlling flow are investigated using steady-state flow properties of the material at different strain rates.

Anelastic to plastic transition in metallic glass-forming liquids.

The configurational properties associated with the transition from anelasticity to plasticity in a transiently deforming metallic glass-forming liquid are studied. The data reveal that the underlying transition kinetics for flow can be separated into reversible and irreversible configurational hopping across the liquid energy landscape, identified with beta and alpha relaxation processes, respe...

Similarities and Differences between the Glass Forming Mechanism in Polymers and Metallic Liquids

Survey of categorization of glass forming mechanisms in liquids based on the known principles reported in the literature is given. The metallic glass-forming liquids can be divided into two types – strong (with high glass forming ability) and fragile (with low glass forming ability). While the bulk amorphous alloys formed from strong liquids do not exhibit sensitivity to low temperature relaxat...

Bond Strength—Coordination Number Fluctuation Model of Viscosity: An Alternative Model for the Vogel-Fulcher-Tammann Equation and an Application to Bulk Metallic Glass Forming Liquids

The Vogel-Fulcher-Tammann (VFT) equation has been used extensively in the analysis of the experimental data of temperature dependence of the viscosity or of the relaxation time in various types of supercooled liquids including metallic glass forming materials. In this article, it is shown that our model of viscosity, the Bond Strength-Coordination Number Fluctuation (BSCNF) model, can be used a...

Five-fold symmetry as indicator of dynamic arrest in metallic glass-forming liquids

With sufficient high cooling rates, a variety of liquids, including metallic melts, will cross a glass transition temperature and solidify into glass accompanying a marked increase of the shear viscosity in approximately 17 orders of magnitude. Because of the intricate atomic structure and dynamic behaviours of liquid, it is yet difficult to capture the underlying structural mechanism responsib...

Structural origin of fractional Stokes-Einstein relation in glass-forming liquids

In many glass-forming liquids, fractional Stokes-Einstein relation (SER) is observed above the glass transition temperature. However, the origin of such phenomenon remains elusive. Using molecular dynamics simulations, we investigate the break- down of SER and the onset of fractional SER in a model of metallic glass-forming liquid. We find that SER breaks down when the size of the largest clust...
