|Abstract:||The dielectric properties, internal friction and Young's modulus of (1-x%)Pb(Mg[sub ⅓]Nb[sub ⅔])O₃-x%PbTi0₃ (for x=13,23,33) ceramics have been measured. A phase-transition like internal friction peak associated with Young's modulus softening has been observed at temperature T[sub R-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. The softening of Young's modulus corresponding to the appearance of polar nano-domains is also found at the temperature far above T[sub m].|
