Using high-pressure torsion to process an aluminum–magnesium nanocomposite through diffusion bonding
Disks of commercial Al-1050 and ZK60A alloys were stacked together and then processed by conventional high-pressure torsion (HPT) through 1 and 5 turns at room temperature to investigate the synthesis of an Al–Mg alloy system. Measurements of microhardness and observations of the microstructures and local compositions after processing through 5 turns revealed the formation of an ultrafine multi...
متن کاملFabrication of hybrid metal systems through the application of high-pressure torsion
This presentation demonstrates a simple and very rapid synthesis of metal matrix nanocomposites (MMNCs) in Al-based hybrid systems which are achieved by processing stacked disks of two pure metals through the application of high-pressure torsion (HPT) at ambient temperature. These synthesized hybrid systems exhibit exceptionally high hardness through rapid deformation-induced diffusion and the ...
متن کاملNumerical Analysis of Severe Plastic Deformation by High Pressure Torsion
High-pressure torsion (HPT) is a metal processing method in which the sample is subjected to a very high plastic shear deformation. This process can produce exceptional levels of grain refinement, and provides a corresponding improvement in mechanical properties. To investigate the stress and strain distribution due to HPT process finite element simulation were conducted to investigate effectiv...
متن کاملSynthesis of 1D Polymer/Zeolite Nanocomposites under High Pressure
Recently, simple carbon based polymers have been synthesized at high pressures in silicalite, a pure SiO2 zeolite with a 3D system of mutually interconnected microchannels. These protocols permitted otherwise unstable polymers to be stabilized and protected from the atmosphere and to obtain an entirely novel class of nanocomposites with modified physical properties. In these 3-D systems, channe...
متن کاملStrong and Stable Nanocomposites Prepared by High-Pressure Torsion of Cu-Coated Fe Powders
Segregation and chemical inhomogeneity are well-known problems in powder metallurgy and are also an issue for new applications of powder mixtures, for example as starting materials for severe plastic deformation. In this study, Cu-coated Fe powder was prepared via immersion deposition, inductively hot-pressed and subsequently deformed using high-pressure torsion. The homogeneity of the pressed ...
