This article focuses on understanding the mechanical behavior of precipitation-hardened
alloys by studying single and polycrystalline deformation behavior with various heat …

The discrepancy between stored energies measured by calorimetry and residual electrical
resistivity, and calculated from dislocation densities measured either by transmission …

A new dislocation density based constitutive model for fcc single crystals at elevated
temperatures is developed. In addition to former composite models [Acta Mater 48 (2000) …

The relationship between the developed intragranular microstructure and the deformation
history of a grain in a low-carbon IF steel is comprehensively investigated during monotonic …

The evolution mechanisms of dislocation microstructures and new grains at high strains of
above 4 were studied by means of multiple compression of a polycrystalline copper (99.99 …

Cyclic deformation under proportional and nonproportional loading of a textured copper was
experimentally studied, and the results were compared with those of texture-free copper with …

A model is proposed for the low temperature tensile response of copper polycrystals with
grain sizes in the range of 2–50μm. The initial work hardening behaviour is strongly grain …

In this paper, modifications are proposed to a phenomenological plasticity model to account
for the evolution of recrystallization and the resultant softening behavior. The novel model …

The present paper is concerned with the development of a micromechanical model of the
hardening, rate-sensitivity and thermal softening of bcc crystals. In formulating the model, we …

High strain rate measurements reported recently for several tantalum and copper
crystal/polycrystal materials are shown to follow dislocation mechanics-based constitutive …
