Ultra-high strength steels are the crucial irreplaceable materials in the fields of aerospace,
national defense and military industries. Unfortunately, it is challenging to achieve the …

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 …

Advanced ultra-high strength steels are highly desirable for a wide range of engineering
applications. Nanoscale co-precipitation strengthening in steels has received increasing …

We report on the alloy design strategies, precipitation mechanism and mechanical
properties of an ultra-high strength steel hardened by co-precipitation of nanoscale NiAl and …

A novel ultra-high strength precipitation hardened martensitic steel with balanced ductility
and creep resistance has been developed. It utilises a unique combination of nanometre …

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 …

Engineering materials processed using additive manufacturing (AM) techniques such as
laser powder bed fusion (LPBF) often exhibit unique microstructures and defects that must …

This present work simulated the coherent BCC/B2 microstructures existing in body-centered-
cubic (BCC)-based Al-Ni-Co-Fe-Cr high entropy alloys (HEAs) in light of the phase-field …

The present work primarily investigates the morphological evolution of the body-centered-
cubic (BCC)/B2 phases in Al x NiCoFeCr high-entropy alloys (HEAs) with increasing Al …

A physics–based modelling framework to describe microstructure and mechanical
properties in maraging steels is presented. It is based on prescribing the hierarchical …
