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…
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…
Atomistic fracture in bcc iron revealed by active learning of Gaussian approximation potential
Lei Zhang, Gábor Csányi, Erik van der Giessen +1
The prediction of atomistic fracture mechanisms in body-centred cubic (bcc) iron is essential for understanding its semi-brittle nature. Existing atomistic simulations of the crack…
The Hierarchical Potential Energy Landscape of Screw Dislocation Motion in Refractory High-entropy Alloys
X. Wang, F. Maresca, P. Cao
High-entropy alloys (HEAs) with concentrated solid solutions are conceived to possess a rugged atomic and energy landscape in which dislocation motion necessarily proceeds to accom…
Atomistic Graph Neural Networks for metals: Application to bcc iron
Lorenzo Cian, Giuseppe Lancioni, Lei Zhang +4
The prediction of the atomistic structure and properties of crystals including defects based on ab-initio accurate simulations is essential for unraveling the nano-scale mechanisms…
Edge Dislocations Can Control Yield Strength in Refractory Body-Centered-Cubic High Entropy Alloys
Francesco Maresca, Chanho Lee, Rui Feng +8
Energy efficiency is motivating the search for new high-temperature metals. Some new body-centered-cubic random multicomponent "high entropy alloys (HEAs)" based on refractory elem…
Mechanistic origin of high retained strength in refractory BCC high entropy alloys up to 1900K
Francesco Maresca, William A. Curtin
The body centered cubic (BCC) high entropy alloys MoNbTaW and MoNbTaVW show exceptional strength retention up to 1900K. The mechanistic origin of the retained strength is unknown y…
Microscopic plasticity and damage in two-phase steels: on the competing role of crystallography and phase contrast
T. W. J. de Geus, F. Maresca, R. H. J. Peerlings +1
This paper unravels micromechanical aspects of metallic materials whose microstructure comprises grains of two or more phases. The local plastic response is determined by (i) the r…
