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…
