| description | The present study aimed to experimentally evaluate the mechanical properties of Pb(In<sub>1/2</sub>Nb<sub>1/2</sub>)O<sub>3</sub>−Pb(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>−PbTiO<sub>3</sub> (PIN−PMN−PT) bulk single crystals with different crystallographic directions using the nanoindentation technique. The load<b>−</b>indentation depth curves, elastic and plastic deformations, hardnesses, and Young’s moduli of [100]- and [110]-oriented 0.28PIN−0.43PMN−0.29PT bulk single crystals were investigated. Our results show that with an increase in the maximum indentation depth <i>h</i><sub>max</sub>, the plastic residual percentage increased for both the [100]- and the [110]-oriented single crystals. At each <i>h</i><sub>max</sub>, the plastic residual percentage of the [100]-oriented PIN−PMN−PT single crystals was less than that of the [110]-oriented PIN−PMN−PT single crystals. At <i>h</i><sub>max</sub> from 500 nm to 2000 nm, the plastic deformation was larger than the elastic deformation, and the plastic residual percentage was larger than 50% for both the [100]- and the [110]-oriented single crystals. This means that the plastic deformation dominated in the indentation process of PIN−PMN−PT single crystals. The indentation size effect on the hardness of the PIN−PMN−PT single crystals was apparent in the nanoindentation process. Both the hardness and the Young’s modulus of the [100]-PIN−PMN−PT single crystals were greater than those of the [110]-PIN−PMN−PT single crystals, which indicates that the PIN−PMN−PT single crystals had anisotropic mechanical characteristics. |
