摘要
The dielectric properties, internal friction, and Young's modulus of (1-x%) Pb(Mg1/3Nb2/3)O-3-x%PbTiO3 (for x=13, 23, and 33) ceramics have been measured. A phase-transition-like internal friction peak associated with Young's modulus softening has been observed at temperature TR-F, which can be attributed to the relaxor-to-ferroelectrics (R-F) phase transition. Therefore, the R-F phase transition can be explained in terms of the paraelectric-to-ferroelectric phase transition of paraelectric matrix in the materials. (C) 2002 American Institute of Physics.
