The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …

This paper provides a synergistic review of the current scenario and future prospects of
aluminum metal matrix composites (AMMCs). AMMCs are advanced materials that have …

TiZrHfNbTa refractory high-entropy alloys (RHEAs) are now at the research frontier of
advanced metallic materials due to their exceptional mechanical performance, particularly at …

Research in the field of high-entropy alloys has been surging since the 2010s. As widely
acknowledged, research interests in this field are largely sparked by the enormous …

Heterostructured materials are an emerging class of materials with superior performances
that are unattainable by their conventional homogeneous counterparts. They consist of …

Nanostructured metals are usually strong because the ultrahigh density of internal
boundaries restricts the mean free path of dislocations. Usually, they are also more brittle …

The high-entropy alloy (HEA) concept was based on the idea that high mixing entropy can
promote formation of stable single-phase microstructures. During the past 15 years, various …

Research on powder-based additive manufacturing of aluminium alloys is rapidly
increasing, and recent breakthroughs in printing of defect-free parts promise substantial …

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 …

Lead-free dielectric ceramics with both a high recoverable energy storage density (W rec)
and excellent mechanical performance are highly desirable for practical applications in next …
