Microstructural evolution in copper subjected to severe plastic deformation: Experiments and analysis
TL;DR: In this article, the evolution of microstructure and the mechanical response of copper subjected to severe plastic deformation using equal channel angular pressing (ECAP) was investigated, and it was shown that the microstructures produced through adiabatic shear localization during high strain rate deformation and ECAP are very similar.
Journal ArticleDOI
Laser-induced shock compression of monocrystalline copper: characterization and analysis
Marc A. Meyers,Fabienne Grégori,Bimal K. Kad,M. S. Schneider,Daniel H. Kalantar,Bruce Remington,Guruswami Ravichandran,T. R. Boehly,Justin Wark +8 more
TL;DR: In this paper, a method for estimating dislocation densities is proposed, based on nucleation of loops at the shock front and their extension due to residual shear stresses behind the front.
Journal ArticleDOI
Microstructural evolution in copper processed by severe plastic deformation
TL;DR: In this article, the mechanisms of microstructural evolution in copper subjected to equal channel angular pressing (ECAP) have been investigated after successive passes, where the first few passes are the most efficient in grain refinement while the microstructure becomes gradually more equiaxed as the number of passes increases.
Journal ArticleDOI
Laser-induced shock compression of copper: Orientation and pressure decay effects
M. S. Schneider,Bimal K. Kad,Marc A. Meyers,Fabienne Grégori,Daniel H. Kalantar,Bruce Remington +5 more
TL;DR: In this paper, a modified mechanical threshold stress (MTS) model is applied to the two orientations, incorporating both slip and twinning, and the threshold pressure for twinning is calculated, considering the effect of shock heating.
Journal ArticleDOI
Properties of {110](111} slip in Al-rich γ-TiAl deformed at room temperature II. The formation of strings of prismatic loops
TL;DR: In this article, two mechanisms for the formation of strings of dislocation loops reported in part I of this work are explored: string formation by coalescence of two jogged segments originating from the same dislocation and local cross-slip annihilation of dipoles formed by two unjogged dislocations.
