High entropy alloys (HEAs) is a new generation of alloys with multi-component systems and
emerged as a potential candidate for the industrial applications due to their excellent …

Conventional alloys are usually based on a single host metal. Recent high-entropy alloys
(HEAs), in contrast, employ multiple principal elements. The strength of HEAs is …

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 …

Nanostructured metallic materials having nanocrystalline and ultrafine-grained structures
show exceptional mechanical properties, eg superior strength, that are very attractive for …

Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Metals can be processed to reach ultra-high strength, but usually at a drastic loss of ductility.
Here, we review recent advances in overcoming this tradeoff, by purposely deploying …

By laser cladding, a FeCrAlMoSi x high entropy alloy (HEA) coating (x= 0, 0.05, and 0.10)
was produced on Ti6Al4V titanium alloy surface to improve its resistance to the influence of …

Refining a metal's grain size can result in dramatic increases in strength, and the magnitude
of this strengthening increment can be estimated using the Hall–Petch equation. Since the …

Coherent twin boundaries (CTBs) are internal planar defects that offer a promising pathway
for designing advanced metallic materials with superior strength-ductility synergy. However …

High entropy alloys (HEAs), offering a multi-dimensional compositional space, provide
almost limitless design opportunities surpassing the frontiers of structural materials …
