On the grain size dependent working hardening behaviors of severe plastic deformation processed metals

, 2020
Based on our analysis, the grain size effect in the most widely used models such as the Kocks–Mecking–Estrin (KME) model cannot account for the work hardening behaviors of nano-crystalline or ultrafine-crystalline metals processed by severe plastic ...

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.

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 ...

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.

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 ...
