Aluminium alloys are being increasingly utilised in the automotive and aerospace industries
to reduce the weight of vehicles. Extensive research has been conducted to overcome the …

In industrial forming processes, the metals and alloys are subject to complex strain, strain-
rate, and temperature histories. Understanding the flow behaviors of metals and alloys in hot …

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 …

Nanocrystalline alloys that exhibit grain boundary segregation can access
thermodynamically stable or metastable states with the average grain size dictated by the …

Nanocrystalline Cr (nc-Cr) was synthesized by electrodeposition. Samples with various
grain sizes (19–57 nm) were prepared by annealing the as-deposited sample …

Carbon nanotubes (CNTs) possess exceptional mechanical properties, and when
introduced into a metal matrix, it could significantly improve the elastic stiffness and plastic …

When the mean grain size is larger than∼ 100nm, it is well accepted for different
heterogeneous materials that the macroscopic yield stress follows the so-called Hall–Petch …

For the first time, high quality bulk nanocrystalline (nc) fcc metals, with least amounts of
imperfections, exhibiting high strength and ductility at room and different temperatures …

Flow stress and work hardening behaviors, as two important aspects of mechanical
behaviors, have been studied extensively and their interpretation for the case of pure metals …

The response of structures and materials subject to impulsive loads remains a field of
intense research. The dynamic loading and temperature increase affect the material's …
