Title: Properties of Dislocation Drag from Phonon Wind at Ambient Conditions

Abstract

It is well known that, under plastic deformation, dislocations are not only created but also move through the crystal, and their mobility is impeded by their interaction with the crystal structure. At high stress and temperature, this “drag” is dominated by phonon wind, i.e., phonons scattering off dislocations. Employing the semi-isotropic approach discussed in detail in a previous paper (J. Phys. Chem. Solids 2019, 124, 24–35), we discuss here the approximate functional dependence of dislocation drag B on dislocation velocity in various regimes between a few percent of transverse sound speed c_T and c_T (where c_T is the effective average transverse sound speed of the polycrystal). In doing so, we find an effective functional form for dislocation drag B(v) for different slip systems and dislocation characters at fixed (room) temperature and low pressure.

On the velocity dependence of the dislocation drag coefficient from phonon wind

Technical Report Blaschke, Daniel N. ; Mottola, Emil ; Preston, Dean Laverne

The phonon wind mechanism, that is, the anharmonic interaction and scattering of phonons by a moving dislocation, imparts a drag force B (v,T,ρ) v on the dislocation. The drag coefficient B has been previously computed and experimentally determined only for dislocation velocities v much less than transverse sound speed, c_T. In this paper we derive an expression for the velocity dependence of B up to c_T in terms of the third-order elastic constants of the crystal. We compute the velocity dependence of the phonon wind contribution to B in the range 1%–90% c T for Al, Cu, Fe, and Nbmore »« less

Velocity dependent dislocation drag from phonon wind and crystal geometry

Journal Article Blaschke, Daniel N. - Journal of Physics and Chemistry of Solids

The mobility of dislocations is an important factor in understanding material strength. Dislocations experience a drag due to their interaction with the crystal structure, the dominating contribution at high stress and temperature being the scattering off phonons due to phonon wind. Yet, the velocity dependence of this effect has eluded a good theoretical understanding. In a previous work, dislocation drag from phonon wind as a function of velocity was computed from first principles in the isotropic limit, in part for simplicity, but also arguing that macroscopically, a polycrystalline metal looks isotropic. However, since the single crystal grains are typically amore »« less

Analytic model of the remobilization of pinned glide dislocations: Including dislocation drag from phonon wind

Journal Article Blaschke, Daniel ; Hunter, Abigail ; Preston, Dean Laverne - International Journal of Plasticity

Here, we discuss the effect of a non-constant dislocation drag coefficient on the very high strain rate regime within an analytic model describing mobile-immobile dislocation intersections applicable to fcc polycrystals. Based on previous work on dislocation drag, we estimate its temperature and pressure dependence and its effects on stress–strain rate relations. In the high temperature regime, we show that drag can remain the dominating effect even down to intermediate strain rates. We also discuss the consequences of having a limiting dislocation velocity, a feature which is typically predicted by analytic models of dislocation drag, but which is somewhat under debatemore »« less

A Report on the use of Weak-Shock Wave Profiles and 3-D Dislocation Dynamics Simulations for Validation of Dislocation Multiplication and Mobility in the Phonon Drag Regime

Technical Report Cazamias, J ; Lassila, D ; Shehadeh, M ; ...

Dynamically loaded gas gun experiments were performed to validate the predictive capabilities of 3-D dislocation dynamics (DD) code simulations at very high strain rates and dislocation velocities where the phonon drag mechanism will be dominant. Experiments were performed in the weak-shock regime on high-purity Mo single crystals with [001] compression axes. We have also performed shock-recovery experiments and are in the process of analyzing the dislocation structure generated by the weak-shock using transmission electron microscopy (TEM), which will also be used to validate the dislocation structure predicted by the DD simulations.
