Abstract At the isothermal annealing below the crystallization temperature, dependences of the internal friction on time for the thin-film nanogranular composite consisting of crystalline nickel (Ni) and an amorphous material based on lead zirconate titanate [Pb0.81Sr0.04(Na0.5Bi0.5)0.15][(Zr0.575Ti0.425)]O3 have been studied. We have observed a relaxation in the amorphous phase of the composite. The structural relaxation studied is irreversible and thermally activated, and dependences of its parameters on temperature and the Ni content are discussed in terms of the model of stress relaxation in local regions of the amorphous material.

摘要 在低于结晶温度的等温退火中，由结晶镍 (Ni) 和基于锆钛酸铅 [Pb0.81Sr0.04(Na0.5Bi0 .5)0.15][(Zr0.575Ti0.425)]O3 已被研究。我们已经观察到复合材料非晶相的弛豫。研究的结构松弛是不可逆的和热激活的，并且根据非晶材料局部区域的应力松弛模型讨论了其参数对温度和 Ni 含量的依赖性。
