Three-dimensional study of grain scale tensile twinning activity in Mg: A combination of microstructure characterization and mechanical modeling
Xun Zeng, Chuanlai Liu, Chaoyu Zhao +3
Tensile twinning is a main deformation mode in hexagonal close packed structure metals, so it is important to comprehensively understand twinning mechanisms which are not fully dis…
Strengthening of Mg-Al-Ca alloys with C15 and C36 Laves phases
Mhammad Zubair, Stefanie Sandlöbes-Haut, Risheng Pei +3
The Laves phase skeleton in cast Mg-Al-Ca alloys is known to provide considerable strengthening. Laves phases such as CaMg (C14), Ca(Al,Mg) (C36), and CaAl2 (C15) have high…
Phase-Field Modeling of Coupled Brittle-Ductile Fracture in Aluminum Alloys
Samad Vakili, Pratheek Shanthraj, Franz Roters +2
Fracture in aluminum alloys with precipitates involves at least two mechanisms, namely, ductile fracture of the aluminum-rich matrix and brittle fracture of the precipitates. In th…
Application-oriented strain-hardening engineering of high-manganese steels
Christian Haase, Franz Roters, Angela Quadfasel
The outstanding mechanical properties of high-manganese steels (HMnS) are a result of their high strain-hardenability. That is facilitated by strong suppression of dynamic recovery…
Understanding the mechanisms of electroplasticity from a crystal plasticity perspective
Arka Lahiri, Pratheek Shanthraj, Franz Roters
Electroplasticity is defined as the reduction in flow stress of a material undergoing deformation on passing an electrical pulse through it. The lowering of flow stress during elec…
Brittle to Quasi-Brittle Transition and Crack Initiation Precursors in Disordered Crystals
S. Papanikolaou, J. Thibault, C. Woodward +2
Crack initiation emerges due to a combination of elasticity, plasticity, and disorder, and it is heavily dependent on the material's microstructural details. In this paper, we inve…
Unraveling the temperature dependence of the yield strength in single-crystal tungsten using atomistically-informed crystal plasticity calculations
David Cereceda, Martin Diehl, Franz Roters +3
We use a physically-based crystal plasticity model to predict the yield strength of body-centered cubic (bcc) tungsten single crystals subjected to uniaxial loading. Our model capt…
