Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Mechanical metamaterials are a class of artificial materials whose geometry is engineered to
have peculiar mechanical properties or programmed responses that are difficult to find in …

Large-scale atomistic computer simulations of materials heavily rely on interatomic
potentials predicting the energy and Newtonian forces on atoms. Traditional interatomic …

The development of advanced structural alloys with performance meeting the requirements
of extreme environments in nuclear reactors has been long pursued. In the long history of …

Thermodynamics is a science concerning the state of a system, whether it is stable,
metastable or unstable, when interacting with the surroundings. In this overview …

Metals usually exist in the form of polycrystalline solids, which are thermodynamically
unstable because of the presence of disordered grain boundaries. Grain boundaries tend to …

Although significant effort has been made on using graphene as a reinforcement in metal
matrix nanocomposites due to its extraordinary high strength and high modulus, metal …

Due to the outstanding creep performance, nickel-based single crystal superalloys (Ni-SXs)
are extensively applied in modern aero-engine and industrial gas turbine. Apart from the …

Transition-metal boron-rich compounds exhibit favorable synthesis conditions and
mechanical properties that hold great promise for wide-ranging applications. However, the …

During the past decade, computer simulations based on a quantum‐mechanical description
of the interactions between electrons and between electrons and atomic nuclei have …
