With the miniaturization of a solid, effects of surface strain and quantum trapping become
increasingly important in determining its properties. As a result, low-dimensional materials …

Abstract Knowledge of the mechanical behaviour of materials is essential in materials
science and applied mechanics. At small sizes, this behaviour shows significant departures …

The contribution of ultrafine grains and nanoscaled precipitates has been investigated in the
Al–Mg–Si system to optimize the combination of strength and electrical conductivity. A full …

Abstract The Hall–Petch relationship σ y= σ 0+ kyd− 0.5 is widely used to describe the
relationship between yield strength and grain size of polycrystalline metals, and the material …

Ultrafine-grained Al alloys produced by high-pressure torsion are found to exhibit a very
high strength, considerably exceeding the Hall–Petch predictions for ultrafine grains. This …

Significant theoretical efforts have been made to understand the Hall-Petch and inverse Hall-
Petch relations of nanocrystalline pure metals, metallic glasses and binary alloy systems …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

NaSICON-type lithium conductor Li1. 3Al0. 3Ti1. 7 (PO4) 3 (LATP) is synthesized with
controlled grain size and composition using solution chemistry. After thermal treatment at …

Lightweighting in the transportation industry is today recognized as one of the most
important strategies to improve fuel efficiency and reduce anthropogenic climate-changing …

Pyrite is the most common authigenic mineral preserved in many ancient sedimentary rocks.
Pyrite also widely exists in the Longmaxi and Wufeng marine shales in the middle Yangtze …
