Nanomechanical characterization of BiFeO[sub]3 ferroelectric ceramicsŽiberna, Katarina ...Ferroelectric perovskites are pivotal in diverse technological applications; however, a gap persists in our comprehension of their mechanical properties, emphasizing the need for additional ... exploration. In the present study, we report on the nanomechanical behavior of BiFeO3 ceramics in the force range between 200 μN and 2 mN, including the evolution of the hardness and the reduced Young’s modulus from (9.9 ± 0.4) GPa and (113.7 ± 6.9) GPa, respectively, with increasing force. A sequence of plastic-deformation mechanisms under the cube-corner probe was revealed through a first pop-in analysis in combination with a variety of electron microscopy techniques, starting with a homogeneous dislocation nucleation, multiplication and rearrangement leading to sub-grain formation, a phenomenon observed in metals but not in ceramics.Source: Journal of the European Ceramic Society [Elektronski vir]. - ISSN 1873-619X (Vol. 44, Iss. 12, 2024, 7 str.)Type of material - e-articlePublish date - 2024Language - englishCOBISS.SI-ID - 195382275
