Heterostructured (HS) materials are a novel class of materials with mechanical properties
that are superior over their conventional homogeneous counterparts. They are composed of …

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 …

Surface severe plastic deformation (S 2 PD) of additively manufactured/three-dimensional
(3D) printed metallic parts is gaining increased attention as a post-manufacturing operation …

A novel brick-mud structure was proposed by introducing cell size gradient design into the
nacre-like brick-mud microstructure. The gradient brick-mud structure samples were …

Synergetic strengthening induced by the coordinated deformation between mechanically
incompatible zones of heterostructured (HS) materials is a new strengthening mechanism …

Here the combination of synergistic strengthening and strain delocalization effects is
realized in high-manganese steel by gradient microstructure designing, which results in an …

Multi-metal composites have gained much interest in recent years to explore the unfilled
space of the strength-elongation window. However, producing these composites is …

Gradient structured (GS) metals can simultaneously achieve high strength and high ductility,
which is the pursuit of structural materials. Abundant studies have pointed out that significant …

The large strength difference between hard and soft components in heterogeneous
structured materials leads to the evolution of high back-stress hardening, which increases …

In this study, gradient-structured Fe x (CoNi) 90− x Cr 10 ferrous medium-entropy alloys
were fabricated by using an ultrasonic nanocrystalline surface modification process. The …
