Dissipation function of the first-order phase transformation in solids via internal-friction measurements

Elastic anomalies associated with transformation sequences in perovskites: II. The strontium zirconate–titanate Sr(Zr,Ti)O3solid solution series

“…Mobile interfaces between coexisting phases at a first order transition can have a similar influence (e.g. Wang et al 2000, Zhang et al 1995a, 1995b, Pérez-Sáez et al 1998, Harrison et al 2004a, Sondergeld et al 2006. As discussed in McKnight et al (2009), transformation twin walls must exist in Pnma, I mma and I 4/mcm structures.…”

Coupling Mechanical and Electrical Properties in Spin Crossover Polymer Composites

“…Such anelastic phenomena are typical in materials with first-order phase transitions and can be associated with the internal frictions during the nucleation and domain growth process. [38,39] In addition to this transitory phenomenon, the loss modulus exhibits also a persisting decrease in the HS phase, particularly pronounced in the PVDF composite (≈40%; see Figure S25c in the Supporting Information), which is indicative of a less viscoelastic behavior with respect to the LS phase. This is also in line with the increase of the storage modulus E′ in the HS form (by ≈8%, see Figure S21a in the Supporting Information).…”

Comparison of internal friction and torsion strain spectra for the cubic–tetragonal transformation of PMN‐32PT crystal

“…Mechanical spectra are sensitive to the structural change inside solid specimens and have been extensively applied to investigate the motion of ferroelectric domains [4], phase transformations [5][6][7], etc. Acoustic emission, one manifestation of bursting strain changes of solid specimens, has been applied to study the evolution of PNRs inside relaxors [8].…”
