Traditional ceramic materials are suboptimal for use in complex environments because of
their brittleness and sensitivity to flaws. As such, developing flexible and elastic ceramic …

Ceramic matrix composites (CMCs) are designed to overcome the main drawback of
monolithic ceramics, namely their brittleness, and are constituently expressed as a …

This study aimed to investigate the effects of the original thickness on the densification,
microstructure, and nanoindentation hardness of silicon carbide (SiC) ceramics prepared by …

The recent observation of the reverse Hall-Petch relation in nanocrystalline ceramics offers a
possible pathway to achieve enhanced ductility for traditional brittle ceramics via the …

The evolution of grain boundary (GB) networks in polycrystalline metals depends not only on
the movement of the constituent GBs but also on the migration of GB triple junctions (TJs) …

Nano-multilayered films offer a multilayer structure arrangement at several to tens of
nanometers. They have hardness, high-temperature oxidation resistance, and low wear …

To develop transparent materials with superior mechanical properties, nanocrystalline
magnesium aluminate (MgAl 2 O 4) spinel with grain sizes ranging from 3.7 to 80 nm has …

Abstract The Orowan‐Petch relation is a famous model to describe the strength of
polycrystalline ceramics covering a wide range of grain sizes. However, it becomes difficult …

CNTs and graphene have revolutionized the microstructural design of metals, polymers and
ceramics, especially in structural and anti-friction applications. This article comprehensively …

Abstract The Hall-Petch and inverse Hall-Petch behaviors in nanocrystalline ceramics are
not well understood because dislocation activities, which are important in metals, are usually …
