Nanocrystalline metals demonstrate a range of fascinating properties, including high levels mechanical strength. However, as these materials are exposed to temperatures, it is critical determine the grain size evolution, this process can drastically change properties. In work, nanocrystalline sputtered Cu thin films with 43 +/- 2 nm were produced by dc-magnetron sputtering. Specimens subsequently annealed in situ transmission electron microscope at 100, 300 and 500 degrees C. Not only was...
The main challenge in the production of metal matrix composites reinforced by carbon nanotubes (CNTs) is development a manufacturing process ensuring dispersion nanoparticles without damaging them, and formation strong bond with metallic to achieve an effective load transfer, so that maximum reinforcement effect CNTs will be accomplished. This research focuses on powder metallurgy aluminum nickel CNTs, using ultrasonication as mixture process. Microstructural characterization nanocomposites...
Additive manufacturing (AM) is one of the most trending technologies nowadays, and it has potential to become disruptive for manufacturing. Academia industry pay attention AM because enables a wide range new possibilities design freedom, complex parts production, components, mass personalization, process improvement. The material extrusion (ME) technology metallic materials becoming relevant equivalent other techniques, like laser powder bed fusion. Although ME cannot overpass some...
The development of metal nanocomposites reinforced by carbon nanotubes (CNTs) remains a focus the scientific community due to growing need produce lightweight advanced materials with unique mechanical properties. However, for successful production these nanocomposites, there is consolidate knowledge about how reinforcement influences matrix microstructure and which are strengthening mechanisms promoting best In this context, investigation focuses on study effect an Ni-CNT produced powder...
Dissimilar diffusion bonds of TiAl alloy to AISI 310 stainless steel using Ni/Ti reactive multilayers were studied in this investigation. The Ni and Ti alternating layers deposited by d.c. magnetron sputtering onto the base materials, with a bilayer thickness 30 60 nm. Joining experiments performed at 700 800 °C for min under pressures 50 10 MPa. effectiveness improve bonding process was assessed microstructural characterization interface mechanical tests. Diffusion bonded joints...
Abstract This research focuses on characterization of the impact dispersion methods aluminum-carbon nanotubes (Al-CNTs) nanocomposite structure. Nanocomposites were produced by a conventional powder metallurgy process after CNTs Al powders, using two approaches: (1) and mixture with powders performed in single step ultrasonication; (2) previously untangled ultrasonication then mixed ball milling. Microstructural Al-CNT nanocomposites was optical microscopy, scanning transmission electron...
In this study, the deposition of martensitic stainless-steel (Metco 42C) powder on 42CrMo4 structural steel by direct laser (DLD) was investigated. Clads were produced varying power, scanning speed, feed rate, and preheating. The effect these processing variables microstructure microhardness clads analyzed, as well their soundness, yield (measured dilution), geometric characteristics (height, width, depth). complex interaction evaluated forced application parameters to systematize clads.
