A comparative study of ultrasonic velocity evaluated from Schaaffs collision factor theory (CFT), Nomoto relation, ideal mixing relation and Junjie relation has been carried out for the Pb-Sn alloy at three different temperatures and at various compositions. The agreement between experimental and theoretical values is quite satisfactory. The computed values of sound velocities from ideal-mixing relation have been used to obtain the degree of molecular interaction. Interaction studies have also been made in terms of excess intermolecular free-length and excess acoustic impedance.

Abstract


A comparative study of ultrasonic velocity evaluated from Schaaffs collision factor theory (CFT), Nomoto relation, ideal mixing relation and Junjie relation has been carried out for the Pb-Sn alloy at three different temperatures and at various compositions. The agreement between experimental and theoretical values is quite satisfactory. The computed values of sound velocities from ideal-mixing relation have been used to obtain the degree of molecular interaction. Interaction studies have also been made in terms of excess intermolecular free-length and excess acoustic impedance.
