A quantitative insight into strain hardening behavior of typical Hadfield steel under dynamic load

open access: yesJournal of Materials Research and Technology, 2023
In this paper, the critical threshold associated to the activating of strain hardening capacity with respect to typical Hadfield steel Mn13Cr2 was explored quantitatively utilizing a Separated Hopkinson Press Bar (SHPB).

Plastic deformation modelling of tempered martensite steel block structure by a nonlocal crystal plasticity model

open access: yesTheoretical and Applied Mechanics Letters, 2014
The plastic deformations of tempered martensite steel representative volume elements with different martensite block structures have been investigated by using a nonlocal crystal plasticity model which considers isotropic and kinematic hardening produced

Strong Strain Hardening in Nanocrystalline Nickel [PDF]

open access: yesPhysical Review Letters, 2009
Low strain hardening has hitherto been considered an intrinsic behavior for most nanocrystalline (NC) metals, due to their perceived inability to accumulate dislocations. In this Letter, we show strong strain hardening in NC nickel with a grain size of approximately 20 nm under large plastic strains.

Orientation Influence on Tensile Strain Hardening in Forged Plates of AA2014 Aluminium Alloy [PDF]

open access: yesArchives of Metallurgy and Materials
Strain hardening is an effective strengthening method for alloys that requires plastic deformation of the material during manufacturing. The strength will significantly increase due to the number of dislocations formed during plastic flow of material ...

Plastic instability in complex strain paths predicted by advanced constitutive equations [PDF]

open access: yes
The present paper aims at predicting plastic instabilities under complex loading histories using an advanced sheet metal forming limit model. The onset of localized necking is computed using the Marciniak-Kuczinslcy (MK) analysis [I] with a physically ...

Tensile Strain Hardening Behavior and Fractography of Superalloy GH39

open access: yesJournal of Aeronautical Materials, 2016
The strain hardening behaviour and fractography of superalloy GH39 was investigated by tensile test at different strain rates. Results indicate that strain hardening behaviours are different during the deformation process.
