Influence of Crystal Plasticity Parameters on the Strain Hardening Behavior of Polycrystals
The effective mechanical properties of a polycrystal depend directly on the single-crystal properties of each grain and its crystallographic orientation with respect to the load axis.

Statistical properties of effective elastic moduli of random cubic polycrystals
The homogenized elastic properties of polycrystals depend on the grain morphology and crystallographic orientations. For simplification purposes, the orientations of the grains are usually considered three independent Euler angles.

The Internal Friction of Single Crystals, Bicrystals and Polycrystals of Pure Magnesium
The internal friction of magnesium single crystals, bicrystals and polycrystals has been studied between room temperature and 450°C. There is no internal friction peak in the single crystals, but a prominent relaxation peak appears at around 160°C in ...

The Dislocation Mechanics of Crystal/Polycrystal Plasticity
A brief history and update are given in four examples demonstrating that polycrystals are generally stronger than their individual component crystal grains because of obstructed dislocation pile-ups at grain boundaries.

Topological and metrical aspects of normal and abnormal grain growth
Grain growth theories normally describe a grain using the concept of ‘grain radius’. However, this assumption bypasses all topological information relating to the grain, viz., the number of its faces, edges, etc. This study, by contrast, introduces a new

A Compact Ultrafast Electron Diffractometer with Relativistic Femtosecond Electron Pulses
We have developed a compact relativistic femtosecond electron diffractometer with a radio-frequency photocathode electron gun and an electron lens system.

Static indentation and dynamic indentation are reviewed, with a focus on extraction of material properties of isotropic strain-hardening polycrystalline metals that may be rate- and temperature-sensitive. Static indentation is reviewed first, followed by
