Microstructure, mechanical behavior and stress corrosion cracking susceptibility in ultrafine-grained Al-Cu alloy
Diogo Pedrino Braga,Danielle Cristina Camilo Magalhães,Andrea Madeira Kliauga,Carlos Alberto Della Rovere,Vitor Luiz Sordi +4 more
TL;DR: In this paper, the simultaneous impact of ECAP processing on microstructure, mechanical strength and SCC resistance of an Al-4wt.%Cu alloy, in comparison with a commercially pure aluminum, is evaluated by optical and electronic microscopy, while mechanical response was evaluated by hardness measurements and tensile tests.
Journal ArticleDOI
Excellent combination of strength and ductility of Al-1.2Mn alloy with multi-scale lamellar structure
TL;DR: In this paper, the multi-scale lamellar structure of ultrafine grains distributed in ribbons with coarse grains was produced in an Al-1.2Mn alloy.

The Deformation and Ageing of Mild Steel: III Discussion of Results
TL;DR: In this paper, an attempt is made to explain the observed phenomena in the yielding and ageing of mild steel, described in two previous papers, in the general terms of a grain-boundary theory.
Journal ArticleDOI
Bulk nanostructured materials from severe plastic deformation
TL;DR: In this article, the authors present methods of severe plastic deformation and formation of nanostructures, including Torsion straining under high pressure, ECA pressing, and multiple forging.
Journal ArticleDOI
Principles of equal-channel angular pressing as a processing tool for grain refinement
TL;DR: In this article, a review examines recent developments related to the use of ECAP for grain refinement including modifying conventional ECAP to increase the process efficiency and techniques for up-scaling the procedure and for the processing of hard-to-deform materials.
Journal ArticleDOI
Using high-pressure torsion for metal processing: Fundamentals and applications
TL;DR: High pressure torsion (HPT) is a well-known technique for metal forming as discussed by the authors, where samples are subjected to a compressive force and concurrent torsional straining.
Journal ArticleDOI
Diffusional Viscosity of a Polycrystalline Solid
TL;DR: In this article, it is suggested that mosaic boundaries and boundaries between grains of nearly the same orientation may not serve as sources or sinks of the diffusion currents, in which case the creep rate will depend only on the configuration of grain boundaries having a sizable orientation differen...
