Metal particles are attractive candidate fuels for various propulsion and energy-conversion
applications, primarily due to their high energy densities. Micron-sized particles present …

The recent development in the field of superhard materials with Vickers hardness of⩾ 40
GPa is reviewed. Two basic approaches are outlined including the intrinsic superhard …

This report deals with the mechanism behind the unusual behavior of nanostructures in
mechanical strength, thermal stability, acoustics (lattice dynamics), photonics, electronics …

Melting of solids is a common phenomenon in nature. It is also one of the most important
phase transformations in materials science and engineering. In recent years, extensive …

Empirical relations are established between the cohesive energy, surface tension, and
melting temperature of different bulk solids. An expression for the size-dependent melting for …

Thermodynamic model first published in 1909, is being used extensively to understand the
size-dependent melting of nanoparticles. Pawlow deduced an expression for the size …

The employment of grain refinement approaches is regarded as a favorable strategy to
increase mechanical properties of duplex stainless steels (DSSs). In this work, a new grain …

Nowadays, many fields are benefiting from manufacturing complex parts with high
performance by selective laser melting (SLM), and particulate-reinforced iron-based metal …

A unified model, free of any adjustable parameters, for the size-dependence and dimension-
dependence of melting point depression and superheating of nanocrystals is developed. In …

Although metal matrix composites (MMCs) possess high mechanical properties for wide
potential applications, there are limited kinds of ex-situ MMCs fabricated via selective laser …
