Computation of phonon dynamics of Mg70Zn30 metallic glass

Phonon Dispersion in Amorphous Ni-Alloys

“…The expressions for longitudinal phonon frequency ω L and transverse phonon frequency ω T per HB approach are [3,[6][7][8]:…”

“…the longitudinal ω L and transverse ω T phonon frequencies are proportional to the wave vectors and obey the relationships [6][7][8] …”

“…All the quantities are computed from the longitudinal and transverse sound velocities (v L and v T ). The bulk modulus B T , modulus of rigidity G, Poisson's ratio σ, Young's modulus Y , and Debye temperature θ D are obtained using the expressions [6][7][8],…”

“…And only recently there has been an explosion of interest to these studies as more promising materials are produced in the amorphous form. The range of applications of metallic glasses is vast and extends from the common window glass to high capacity storage media for digital devices [1][2][3][4][5][6][7][8].…”

Phonon dynamics of glassy copper alloys

“…Theoretical understanding of these structures has been difficult to achieve because of the lack of translational symmetry, both for disordered crystalline alloys and amorphous or glassy alloys. The possible application of transition metal alloys is in microelectronics or as thin-film coating [1][2][3][4][5][6][7][8][9].…”
