Gradient structures found in biological materials have served as a source of inspiration for
scientists seeking to enhance the performance of metals and alloys over the past decades …

Most of the challenges experienced by many engineering materials originate from the
surface which later leads to total failure, hence affecting the resultant mechanical properties …

CoCrFeMnNi high-entropy alloys (HEAs) are additively manufactured by laser directed
energy deposition (L-DED) and laser powder bed fusion (L-PBF) processes. Comparative …

Experiments have shown that a gradient design, in which grain size spans over four orders
of magnitude, can make strong nanomaterials ductile. This chapter presents a developed …

Gradient nano-grained (GNG) materials, inside which grain size increases gradually from
nano-scale in the surface to micro-scale in the substrate, have shown synergetic strength …

The harmonic structure is a recently introduced concept paving the way for engineering
metallic materials to achieve excellent mechanical performance. They consist of soft coarse …

In this study, a high-strain rate ultra-precision machining technology named single point
cubic boron nitride turning is developed to fabricate a gradient nanotwinned CrCoNi …

The effect of back stress on the mechanical behaviors of heterogeneous material is studied
in two modeled heterogeneous laminates, ie laminated structure with a nanostructured (NS) …

Abstract Al/Ti/Al laminated metal composites (LMCs), with layer thicknesses≥ 800 μm, were
fabricated via hot rolling bonding and annealing. The fabricated Al/Ti/Al LMCs displayed …
