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 ...

Multiscale investigations of severe plastic deformation

Materials Science and Engineering: A, 2005
Abstract The present paper represents the results of an application of the multiscale approach to study severe plastic deformation (SPD). These investigations were used to reveal the features of material flow and crystallographic texture development in bulk Cu ingots subjected to SPD by equal-channel angular (ECA) pressing.

The Role of Hydrostatic Pressure in Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractThe contribution presents several experimental examples which show that the presence of an enhanced hydrostatic pressure—as compared to conventional large deformation modes—is one of the main features of severe plastic deformation (SPD). At the example of systematic high pressure torsion experiments with Cu at room temperature, strength ...

Effect of rapid quenching and severe plastic deformation on silver

International Journal of Materials Research, 2012
Abstract Pure silver has been rapidly quenched (RQ) in ribbon form by means of planar flow casting with different cooling rates, obtained with different velocities of the cooling wheel. Ingots of pure silver have been subjected to severe plastic deformation (SPD) using constrained groove pressing and equal-channel angular pressing.

Equivalent Strains in Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractThe concept of equivalent plastic strain is discussed. Definitions may be based on kinematic arguments (like change of geometry) or on equivalence of plastic work. Complications arise when strain is accumulated in increments with variable strain path.

Metal processing by severe plastic deformation

Russian Metallurgy (Metally), 2006
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 characteristic of a deformation mode is determined by the distribution of strain rates over the principal
