Phase Transformation Kinetics Model for Metals
Daniel N. Blaschke, Abigail Hunter, Dean L. Preston
We develop a new model for phase transformation kinetics in metals by generalizing the Levitas-Preston (LP) phase field model of martensite phase transformations (see Levitas and P…
Experimental and theoretical confirmation of an orthorhombic phase transition in niobium at high pressure and temperature
Daniel Errandonea, Leonid Burakovsky, Dean L. Preston +8
Compared to other body-centered cubic (bcc) transition metals Nb has been the subject of fewer compression studies and there are still aspects of its phase diagram which are unclea…
On the temperature and density dependence of dislocation drag from phonon wind
Daniel N. Blaschke, Leonid Burakovsky, Dean L. Preston
At extreme strain rates, where fast moving dislocations govern plastic deformation, anharmonic phonon scattering imparts a drag force on the dislocations. In this paper, we present…
Analytic model of the remobilization of pinned glide dislocations: including dislocation drag from phonon wind
Daniel N. Blaschke, Abigail Hunter, Dean L. Preston
In this paper 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 dislocati…
Dislocation drag from phonon wind in an isotropic crystal at large velocities
Daniel N. Blaschke, Emil Mottola, Dean L. Preston
The anharmonic interaction and scattering of phonons by a moving dislocation, the photon wind, imparts a drag force on the dislocation. In early studies the drag coe…
