Equivalent and effective strains during severe plastic deformation (SPD)

Autor: V. M. Segal

Publikováno v: Philosophical Magazine Letters. 98:511-520

This paper considers the characteristics of severe plastic deformation (SPD) to estimate its efficacy and to compare different processing techniques. In contrast to effective strains by von Mises a...

Quantitative Microstructural Characterization of Thick Aluminum Plates Heavily Deformed Using Equal Channel Angular Extrusion

Autor: V. M. Segal, Oleg Mishin, S. Ferrasse

Publikováno v: Mishin, O, Segal, V M & Ferrasse, S 2012, ' Quantitative Microstructural Characterization of Thick Aluminum Plates Heavily Deformed Using Equal Channel Angular Extrusion ', Metallurgical and Materials Transactions A: Physical Metallurgy and Materials Science, vol. 43, pp. 4767-4776 . https://doi.org/10.1007/s11661-012-1287-1

A detailed quantitative analysis of the microstructure has been performed in three orthogonal planes of 15-mm-thick aluminum plates heavily deformed via two equal channel angular extrusion (ECAE) routes. One route was a conventional route A with no r

Grain structure and texture in aluminium alloy AA5083 after equal angular channel extrusion, warm rolling and subsequent annealing

Autor: D J Lloyd, H. Jin, M Gallerneault, V M Segal, P J Young

Publikováno v: Materials Science and Technology. 27:789-792

An aluminium alloy AA5083, having a submicrometre grain structure generated by equal angular channel extrusion, was rolled at ∼200°C to make flat sheets with 37·5 to 75% thickness reductions. The evolution of grain structure and texture upon warm

Metal processing by severe plastic deformation

Autor: V. M. Segal

Publikováno v: Russian Metallurgy (Metally). 2006:474-483

The mechanics of severe plastic deformation (SPD) is considered. Unlike steady-state plastic flows with the continuous evolution of dislocation structures, the SPD-induced microlocalization strongly depends on the deformation mode. The quantitative c
