Design and microstructural analysis of magnesium alloys for dynamical applications
TL;DR: A microanalytical characterization of cast magnesium alloys of eutectic origin based on the Mg-Al-Ca ternary matrix system has been carried out in order to investigate the influence of alloying elements on their microstructure as mentioned in this paper.

TL;DR: In this paper, the hydrogen desorption process is marked by a dramatic drop of the resonance frequency and by an internal friction peak that occurs under high vacuum at about 580 K.

The structure of high-angle grain boundaries
TL;DR: In this paper, a superimposed dislocation network is proposed for the cubic system, which is a natural extension of previous dislocation models and models based on coincidence relationships, and explains many of the observed properties of grain boundaries.

Experimental Evidence of the Viscous Behavior of Grain Boundaries in Metals
TL;DR: In this paper, a simple torsional apparatus has been devised for measuring four types of anelastic effects at very low stress levels, namely, internal friction at low frequencies, variation of dynamic rigidity with temperature, creep under constant stress, and stress relaxation at constant strain.

The mechanism of grain boundary migration
TL;DR: In this paper, it was shown by electron transmission microscopy that a grain boundary has a step-like structure and the steps are formed by a Frank spiral mechanism or at junction points of grain boundaries.
Journal ArticleDOI
Theory of grain boundary migration rate
TL;DR: In this paper, the migration rate of a grain boundary is calculated as a function of the orientation of the two grains relative to the grain boundary and the thermodynamic constants (driving force, enthalpy of migration etc.).

Stress Relaxation across Grain Boundaries in Metals
TL;DR: In this paper, the temperature dependence of internal friction and rigidity modulus of 99.991 percent aluminum have been measured as a function of frequency of torsional vibration and grain size of the specimen.
