As important structural materials widely used in aerospace and automotive industries,
aluminum alloys are perfect candidates for development of laser metal additive …

The indentation size effect is one of several size effects on strength for which “smaller is
stronger.” Through use of geometrically self-similar indenters such as cones and pyramids …

In metallurgy, mechanical deformation is essential to engineer the microstructure of metals
and to tailor their mechanical properties. However, this practice is inapplicable to near-net …

A strength-ductility trade-off usually occurs when grains are refined to increase strength. A
question arises on if there exists a grain size for the best strength-ductility combination, ie …

Heterostructured metals possess superior mechanical properties exceeding the prediction
by the rule-of-mixtures. However, it remains a challenge to understand the key …

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 …

In metal matrix composites, a metal is combined with another, often nonmetallic, phase to
produce a novel material having attractive engineering attributes of its own. A subject of …

High-capacity electrodes in Li-ion batteries inevitably undergo a large volume deformation
originating from high diffusion-induced stresses during charging and discharging processes …

Over the last three decades, a number of researchers have used the gradient-enhanced
plasticity theory to model the microstructural material behavior, which is not able to be …

Deformation mechanism-based constitutive modeling can serve as a flexible tool to optimize
the microstructure of hetero-structured metals for achieving better mechanical performance …
