TL;DR: It is shown that AA7075 can be safely arc welded without hot cracks by introducing nanoparticle-enabled phase control during welding by adding nanoparticles to a weld filler rod.

TL;DR: Aluminum reinforced by nanoparticles can be deposited layer-by-layer via laser melting of nanocomposite powders, which enhance the laser absorption by almost one order of magnitude compared to pure aluminum powders.

TL;DR: A new discovery is reported that nanoparticles can refine metal grains to ultrafine/nanoscale by instilling a continuous nucleation and growth control mechanism during slow cooling, which overcomes the grain refinement limits.

TL;DR: It was found that besides of growth restriction factor by pinning behavior on grain boundries, TiC nanoparticles served as both an effective nucleation agent for primary grains and an effective secondary phase modifier in AA7075, and the mechanical properties of nano-treated aluminum alloys were improved over those of the pure alloy.

TL;DR: In this article, a detailed thermal analysis and microstructure study were carried out to investigate the nanoparticle-enabled principal mechanisms of hot cracking elimination in high performance aluminum alloys, such as 7075, 6061, and 2024.
