Origin of the yield stress anomaly in L12 intermetallics unveiled with physically-informed machine-learning potentials
Xiang Xu, Xi Zhang, Erik Bitzek +2
The yield stress anomaly of L12 intermetallics such as Ni3Al or Ni3Ga is controlled by the so-called Kear-Wilsdorf lock (KWL), of which the formation and unlocking are governed by…
On the temperature and chemical dependency of prismatic stacking faults in C14 Laves phases
Zhuocheng Xie, Dimitri Chauraud, Erik Bitzek +2
Activation of non-basal slip is essential in improving the deformability of hexagonal crystals. However, the mechanism of non-basal slip remains largely unknown, especially for com…
Thermally activated nature of synchro-Shockley dislocations in Laves phases
Zhuocheng Xie, Dimitri Chauraud, Achraf Atila +3
Synchro-Shockley dislocations, as zonal dislocation, are the major carrier of plasticity in Laves phases at high temperatures. The motion of synchro-Shockley dislocations is compos…
LEFM is agnostic to geometrical nonlinearities arising at atomistic crack tips
Tarakeshwar Lakshmipathy, Paul Steinmann, Erik Bitzek
Various fields such as mechanical engineering, materials science, etc., have seen a widespread use of linear elastic fracture mechanics (LEFM) at the continuum scale. LEFM is also…
A new method for microscale cyclic crack growth characterization from notched microcantilevers and application to single crystalline tungsten and a metallic glass
S. Gabel, B. Merle, E. Bitzek +1
The lifetime of most metals is limited by cyclic loads, ending in fatigue failure. The progressive growth of cracks ends up in catastrophic failure. An advanced method is presented…
