On the influence of Al-concentration on the fracture toughness of NiAl: microcantilever fracture tests and atomistic simulations

Ralf Webler, Polina N. Baranova, Shivraj Karewar +5

The mechanical properties of the stoichiometric B2 $\beta$-phase of NiAl are well established, however the effect of off-stoichiometric composition on the fracture toughness has not ye…
