Kinetics of ferroelastic domain switching with and without back-switching events: A phase-field study
I am pleased to share our first open-access article of 2025! just published in #ActaMaterialia.
In our study, we uncover new insights into the kinetics and motion of domain walls during ferroelastic deformation in yttria-stabilized zirconia. For the first time, we show that domain switching is primarily driven by the propagation of domain walls, with minimal contribution from domain nucleation. We observe that the domain wall velocity follows the KAI model under constant stress, but accelerates under varying loads. Our research also reveals complex behaviors like back-switching and re-switching, leading to significant deviations from KAI kinetics and increased energy absorption. These findings are critical for understanding the performance degradation in applications such as volatile memory and sensors.
