Ductile rupture in metals is a phenomenon that affects a wide range of applications from
forming of automotive body panels to failure of pressure vessels. The incipient stage …

Metallurgists have long been accustomed to a trade-off between yield strength and tensile
ductility. Extending previously known strain-hardening mechanisms, the emerging multi …

Although high-entropy materials are excellent candidates for a range of functional materials,
their formation traditionally requires high-temperature synthetic procedures of over 1,000° C …

The CoCrNi medium-entropy alloy (MEA) has been proven to have excellent mechanical
properties under cryogenic temperatures. Its low yield strength, however, limits practical …

Coarse-grained materials are widely accepted to display the highest strain hardening and
the best tensile ductility. We experimentally report an attractive strain hardening rate …

Widespread interest has been generated by the high-entropy alloys (HEAs) due to their
exceptional ability to combine high plasticity and high strength. However, there is still no …

Multiprincipal-element alloys are an enabling class of materials owing to their impressive
mechanical and oxidation-resistant properties, especially in extreme environments,. Here …

Traditional high strength engineering alloys suffer from serious surface brittleness and
inferior wear performance when servicing under sliding contact at cryogenic temperature …

In this study, we investigated the evolution of a hierarchical multiphase structure in an as-
cast CrMnFeNiCu high-entropy alloy (HEA). Thermodynamic calculations were performed to …

An additively manufactured (nominally equiatomic) CrCoNi alloy was processed by laser
powder bed fusion (LPBF). At ambient temperatures (298 K), this medium-entropy alloy …
