This paper reviews the recent research and development of high-entropy alloys (HEAs).
HEAs are loosely defined as solid solution alloys that contain more than five principal …

Abstract Face-centered-cubic (fcc) type high entropy alloys (HEAs) exhibit outstanding
ductility even at the liquid nitrogen temperature, but they are relatively weak in strength …

Next-generation high-performance structural materials are required for lightweight design
strategies and advanced energy applications. Maraging steels, combining a martensite …

Metallic alloy design for room temperature applications typically aims at avoiding undesired
brittle intermetallic phases. In transition metal alloys, the sigma phase is particularly known …

Control of discontinuous and continuous precipitation is crucial for tailoring the
microstructure and mechanical properties of NiAl-strengthened steels. Through a …

High-performance conventional engineering materials (including Al alloys, Mg alloys, Cu
alloys, stainless steels, Ni superalloys, etc.) and newly-developed high entropy alloys are all …

Additive manufacturing of a low carbon Fe–Cr–Ni–Al maraging stainless steel (with the
brand name CX) through the laser-powder bed fusion (LPBF) process is studied. Since the …

The critical role of Mn partitioning in the formation of ordered NiAl nanoparticles in ferritic
steels has been examined through a combination of atom probe tomography (APT) and …

There have been numerous efforts to develop creep-resistant materials strengthened by
incoherent particles at high temperatures and stresses in response to future energy needs …
