Abstract Scope |
The statistical nature of the transition from purely elastic to plastic deformation (i.e., “pop-in” behavior manifested as a sudden displacement excursion in load-displacement curve) in medium-/high-entropy alloys is explored. A series of nanoindentation tests with three spherical tips having different radii were performed on both face-centered-cubic and body-centered-cubic alloys in hydrogen-charged and uncharged state. The obtained results were systematically discussed in terms of the tip radius effect on the stochastic characteristics of the yielding behavior and its interplay with hydrogenation. |
