+SSLIP: Automated Radon-Assisted and Rotation-Corrected Identification of Complex HCP Slip System Activity Fields from DIC Data
T. Vermeij, G. Slokker, C. J. A. Mornout +2
Identification of crystallographic slip in metals and alloys is crucial to understand and improve their mechanical behavior. Recently, a novel slip system identification framework,…
Discrete slip plane analysis of ferrite microtensile tests: On the influence of dislocation source distribution and non-Schmid effects on slip system activity
J. Wijnen, J. P. M. Hoefnagels, M. G. D. Geers +1
The slip system activity in microtensile tests of ferrite single crystals is compared with predictions made by the discrete slip plane model proposed by Wijnen et al. (Internationa…
An effective anisotropic visco-plastic model dedicated to high contrast ductile laminated microstructures: Application to lath martensite substructure
V. Rezazadeh, R. H. J. Peerlings, F. Maresca +2
In particular types of layer- or lamellar-like microstructures such as pearlite and lath martensite, plastic slip occurs favorably in directions parallel to inter-lamellar boundari…
On the critical role of martensite hardening behavior in the paradox of local and global ductility in dual-phase steels
V. Rezazadeh, R. H. J. Peerlings, J. P. M. Hoefnagels +1
Experimental findings in the literature reveal that DP steels with identical strength and composition, but different microstructures, exhibit inconsistent trends under either necki…
Influence of orientation-dependent lath martensite yielding on the hardening behavior of quenched martensitic steels
V. Rezazadeh, R. H. J. Peerlings, J. P. M. Hoefnagels +2
The onset of plasticity in quenched martensitic microstructures is characterized by a low initial yield stress followed by an extremely strong initial hardening response, and then…
Extensive anisotropic lath martensite plasticity in dual-phase steels: A numerical-experimental investigation
V. Rezazadeh, R. H. J. Peerlings, T. Vermeij +3
This work presents a detailed experimental-numerical analysis of a low-carbon dual-phase steel microstructure, revealing evidence of significant anisotropic plastic deformation in…
Automated Identification of Slip System Activity Fields from Digital Image Correlation Data
Tijmen Vermeij, Ron Peerlings, Marc Geers +1
Crystallographic slip system identification methods are widely employed to characterize the fine scale deformation of metals. While powerful, they usually rely on the occurrence of…
Plasticity, localization, and damage in ferritic-pearlitic steel studied by nanoscale digital image correlation
Tijmen Vermeij, Johan Hoefnagels
The evolution of deformation from plasticity to localization to damage is investigated in ferritic-pearlitic steel through nanometer-resolution microstructure-correlated SEM-DIC (u…
Demonstrating the potential of Accurate Absolute Cross-grain Stress and Orientation correlation using Electron Backscatter Diffraction
Tijmen Vermeij, Marc De Graef, Johan Hoefnagels
We report a first exploration of High-angular-Resolution Electron Backscatter Diffraction, without using simulated Electron Backscatter Diffraction patterns as a reference, for abs…
Systematic and objective identification of the microstructure around damage directly from images
T. W. J. de Geus, C. Du, J. P. M. Hoefnagels +2
An original experimental approach is presented to automatically determine the average phase distribution around damage sites in multi-phase materials. An objective measure is found…
