We review some of the factors that influence the hardness of polycrystalline materials with
grain sizes less than 1 µm. The fundamental physical mechanisms that govern the hardness …

This review summarizes recent advances in the area of tribology based on the outcome of a
Lorentz Center workshop surveying various physical, chemical and mechanical phenomena …

A detailed analysis has been conducted of Ti–6Al–4V processed by metallic shot peening
and laser shock peening. Analysis by incremental hole drilling, electron backscattered …

The motion of line defects (dislocations) has been studied for more than 60 years, but the
maximum speed at which they can move is unresolved. Recent models and atomistic …

In this paper, the interaction between an edge dislocation and irradiation< 100> sessile self-
interstitial atom (SIA) type dislocation loops (DLs) is studied by atomistic simulations in BCC …

This article offers a comprehensive experimental and theoretical study of the causes of
thermal hardening in FCC Al and BCC Fe at high strain rates, with the aim to shed light on …

High speed dislocations have long been identified as the dominant feature governing the
plastic response of crystalline materials subjected to high strain rates, controlling …

This article examines the time to activate Frank–Read sources in response to macroscopic
strain rates ranging from 10 1 s− 1 to 10 10 s− 1 in aluminium under athermal conditions. We …

Hydrogen (H), emerging as a sustainable and promising clean energy source, holds
significant potential for transitioning towards a H-based economy, offering a cleaner …

The interaction between a high speed edge dislocation and a microvoid has been
investigated by molecular dynamics (MD) simulations in BCC crystals of Ta, Fe, V and W in …
