Paper Abstract

Relaxor ferroelectric single crystals produce extraordinary strain levels in response to electric field, but the response is highly dependent on temperature and bias stress. This behavior must be well characterized for the successful development of actuation and sensor applications. This paper presents the results of experimental characterization of <001> oriented single crystal PMN-xPT (x = 0.27 and 0.29) is presented for combined electrical and mechanical loading at various temperatures. These data are contrasted with previously reported constitutive behavior of <001> single crystal PMN-xPT with different compositions. The effects of composition on the phase transformation behavior and linear material properties are compared and discussed.
