Elastic Properties of Substitutional Solid Solutions InxTl1-xI and Sound Wave Velocities in Them

Section: Solid Matter
Original Author's Text: Ukrainian/English

Abstract: Elastic properties of substitutional solid solutions InxTl1-xI have been studied. The corresponding Young modulus, shear modulus, and compression modulus are calculated theoretically. The
dependence of the elastic properties of the InxTl1-xI solid solution on the content within the
interval 0.375 ≤ x ≤ 1 is analyzed. The velocity of sound propagation in examined specimens
is studied experimentally. The obtained data are used to calculate the elastic coefcient C22 for
InxTl1-xI. The theoretical results are found to be in good agreement with experimental data.

Key words: substitutional solid solutions, elastic constants, piezoelectric transducer, ultrasonic waves.
