Viscosity of glass-forming liquids.
The low-temperature dynamics of ultraviscous liquids hold the key to understanding the nature of glass transition and relaxation phenomena, including the potential existence of an ideal thermodynamic glass transition. Unfortunately, existing viscosity models, such as the Vogel-Fulcher-Tammann (VFT) and Avramov-Milchev (AM) equations, exhibit systematic error when extrapolating to low temperatur...
متن کاملThermoviscoelasticity of glass-forming liquids
In supercooled liquids structural relaxation shows up as a frequency dependence of mechanical and thermal properties such as the adiabatic bulk modulus, Ks, shear modulus, G, expansion coecient, ap, and isobaric speci®c heat, cp. Whereas Ks and G can be measured directly, we claim this is dicult for cp. Near the glass transition where cp diers signi®cantly from the isochoric speci®c heat, cv...
متن کاملA Cooperative Shear Model for the Rheology of Glass-Forming Metallic Liquids
2.1 Abstract A rheological law based on the concept of cooperatively sheared flow zones is presented, in which the effective thermodynamic state variable controlling flow is identified to be the isoconfigurational shear modulus of the liquid. The law captures Newtonian as well as non-Newtonian viscosity data for glass-forming metallic liquids over a broad range of fragility. Acoustic measuremen...
متن کاملInvestigation of Cavitation in Glass- Forming Liquids
In an effort to better understand the source of toughness in metallic glass, we have investigated cavitation in glass-forming liquids. When subjected to negative hydrostatic pressure, a liquid will reduce its energy through the formation of a cavity. This phenomenon is the competing process to shear band growth and the development of a large plastic zone, which we have identified as the crucial...
متن کاملA cryostat and temperature control system optimized for measuring relaxations of glass-forming liquids.
An experimental setup, including a cryostat and a temperature control system, has been constructed to meet the demands of measuring linear and nonlinear macroscopic relaxation properties of glass-forming liquids in the extremely viscous state approaching the glass transition. In order to be able to measure such frequency-dependent response functions accurately (including dielectric permittivity...
