In statistical terms, the configurational entropy, S conf , of a structure of fixed configuration is zero, i.e., its Ω=1 in the Boltzmann equation, S conf =k B lnΩ. On that basis, a recent discussion has drawn two inferences: (a) S conf is lost when a liquid vitrifies and thus a glass has no residual entropy, S res , and (b) structural relaxation of a glass...
A novel method to study crystallization behavior in non-crystalline materials has been developed. The method is based on slowing down of sample deformation by viscous flow above the glass transition due to macroscopic crystal growth. This process might be detected by thermomechanical analysis (TMA). The influences of sample length, applied force and heating rate have been examined. Newly developed...
