Ceramics face an everlasting challenge from their intrinsic brittleness at room temperature,
which can lead to early-stage catastrophic failures. The fatal disadvantage primarily results …

The quest for room-temperature ductile ceramics has been repeatedly fueled by hopes for
large-scale applications but so far has been not successful. Recent demonstrations of …

Super strength and toughness, excellent deformation resistance, and high-temperature
service performance are the key factors to determine the practical application of new thermal …

Metallic materials, although composed of metallic bonds, exhibit a wide range of mechanical
properties: some are ductile and deformable, while others undergo a pronounced ductile-to …

While ceramic materials are widely used in our society, their understanding of the plasticity
is not fully understood. MgO is one of the prototypical ceramics, extensively investigated …

A multiphase high‐entropy diboride (Ti0. 25Ta0. 25Hf0. 25Zr0. 25) B2 is obtained by spark
plasma sintering from a mixture of single‐metal diborides. The as‐prepared material at the …

From nanoscale devices including sensors, electronics, or biocompatible coatings to
macroscale structural, automotive or aerospace components, fundamental understanding of …

The strength of refractory ceramics is much limited by their brittleness. Counterintuitively, we
observe simultaneous high hardness and metallic-like ductility in highly overstoichiometric …
