Study of the fatigue endurance and mechanical strength of solid solutions of the PZT–PZN–PMN system, modified with Ba and Sr, corresponding to the formula (Pb[Formula: see text]Sr[Formula: see text]Ba[Formula: see text] [[Formula: see text][Formula: see text]([Formula: see text][Formula: see text] ([Formula: see text][Formula: see text]]O 3 , with [Formula: see text] = 0.02 ÷ 0.12; [Formula: see text] = 0.02, [Formula: see text] = 0.0036 ÷ 0.073; [Formula: see text]= 0.385 ÷ 0.430, [Formula: see text]= 0.402 ÷ 0.447 is presented. It is shown that the evolution of the polarization characteristics with an increase in the number of repolarization cycles, [Formula: see text], is characterized by two sections: slow fatigue and logarithmic evolution. It was found that an increase in the strontium content shifts the beginning of the logarithmic stage towards to the large [Formula: see text]. It is shown that an increase in the average grain size decreases the mechanical strength. A conclusion is made about the expediency of using the obtained data in the development of devices operating in power modes.
