Twin boundaries (TBs) are ubiquitous interfaces with specific structure in metallic materials.
They possess special interactions with dislocations and the fatigue cracking behaviors are …

A great research effort is being employed in the development of Multi-Principal Element
Alloys (MPEAs). The major interest on these alloys lies in the vast compositional field in …

Understanding the fundamental of contact-induced behavior in metals is critical for the
studies of associated mechanical properties. Although nanocontact plasticity in the …

Face-centered cubic single-phase high-entropy alloys (HEAs) containing multi-principal
transition metals have attracted significant attention, exhibiting an unprecedented …

Single-phase face-centered cubic (SP-FCC) alloys normally possess low strength.
Conventionally strengthening strategies inevitably cause significant ductility sacrifice. Here …

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

We report on the low-cycle fatigue behavior of single-phase, face-centered cubic CoCrNi
and CoCrFeMnNi at room temperature. Both alloys manifest cyclic hardening followed by …

While material design and mechanical properties have been extensively investigated in
medium entropy alloy (MEA), resources are no available to evaluate more complex …

The present study investigates the crystallographic-texture effects on the improved fatigue
resistance in the CoCrFeMnNi high-entropy alloys (HEAs) with the full-size geometry of the …

Laser-based directed energy deposition (LDED) enables the rapid near-net-shape
fabrication of large-scale titanium components for aerospace applications. However, the …
