Conventional methods fail to measure cp„ ... of glass-forming liquids
The specific heat is frequency dependent in highly viscous liquids. By solving the full one-dimensional thermoviscoelastic problem analytically it is shown that, because of thermal expansion and the fact that mechanical stresses relax on the same time scale as the enthalpy relaxes, the plane thermal-wave method does not measure the isobaric frequency-dependent specific heat cp . This method rat...
متن کاملViscosity 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 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 کاملStructural disorder in metallic glass-forming liquids
We investigated structural disorder by a new structural parameter, quasi-nearest atom (QNA), in atomistic configurations of eight metallic glass-forming systems generated through molecular dynamics simulations at various temperatures. Structural analysis reveals that the scaled distribution of the number of QNA appears to be an universal property of metallic liquids and the spatial distribution...
