Severe Plastic Deformation - A Review

Materials Today: Proceedings, 2018
Abstract Severe plastic deformation is one of the methods widely used for producing a fine-grained structure throughout the volume. Different SPD methods have been used for producing a fine-grained and ultra-fine grained structure which effectively alters the microstructure and in turn improve the properties.

Severe Plastic Deformation

2020
This chapter presents the production of light alloys (Ti-Mg) by severe plastic deformation. Alloys with different Mg content were synthesized by high-pressure torsion straining, technique that allows to obtain ultrafine-grained materials in both equilibrium and nonequilibrium, changing the chemical, thermodynamic, and mechanical properties of the ...

Fracture of severely plastically deformed titanium

Materials Letters, 2022
Abstract The mechanical properties with emphasis on the fracture behaviour of ultrafine-grained Ti processed by high pressure torsion were evaluated. Through this process a substantial refinement of the microstructure was induced. As a consequence, a pronounced increase of tensile strength was achieved compared to conventional Ti while the ductility ...

Development of structure and properties in bimetallic Al/Cu sandwich composite during cumulative severe plastic deformation

Journal of Sandwich Structures and Materials, 2021
Development of modern materials is non-negligibly connected with enhancement of their mechanical and utility properties, which can advantageously be performed via optimized deformation processing.

Paradoxes of Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractSevere plastic deformation (SPD) can lead to emergence of microstructural features and properties in materials which are fundamentally different from the ones well known for conventional cold deformation. In particular, the instances of unusual phase transformations resulting in development of highly metastable states associated with formation ...

Severe Plastic Deformation of Amorphous Alloys

Materials Science Forum, 2008
The structure and mechanical properties of amorphous alloy Ni44Fe29Co15Si2B10 after severe plastic deformation (SPD) in Bridgman chamber at the different temperatures (77 and 298 K) have been studied. It is shown that the early stages of the SPD of amorphous alloy cause a noticeable decrease in microhardness HV and significant changes in the physical ...

Processing Metals by Severe Plastic Deformation

Solid State Phenomena, 2005
Severe plastic deformation (SPD) is used to convert traditional coarse grain metals and alloys into ultrafine-grained (UFG) materials. UFG materials possess a number of improved mechanical and physical properties which destine them for a wide commercial use.

Mechanical Alloying and Severe Plastic Deformation

2007
Recently developed methods for materials processing, such as mechanical alloying, cryomilling, friction stir processing, equal-channel angular pressing, and high-pressure torsion, are reviewed in the present chapter. Over the last two decades, there has been increasing interest on the synthesis of advanced materials using mechanical alloying, and ...

Severe plastic deformation of a TWIP steel

Materials Science and Engineering: A, 2014
Abstract The severe plastic deformation of a Twinning Induced Plasticity (TWIP), 0.61C–22.3Mn–0.19Si–0.14Ni–0.27Cr (wt%) steel by Equal Channel Angular Pressing (ECAP) at elevated temperatures was used to study the deformation mechanism as a function of accumulated strain and processing parameters.

The Limits of Refinement by Severe Plastic Deformation

Advanced Engineering Materials, 2006
AbstractThe effect of the different processing parameters on the refinement during severe plastic deformation is evaluated. The attention is focused to very high strains, where saturation in the structural refinement is observed. The single phase metals and alloys show a relatively uniform behaviour, with increasing strain the size of structural ...
