Popis:	The compositional dependence of elastic properties of Al3+-substituted Bi(Pb)-2223 superconducting system with the general formula Bi1.7−x AlxPb0.3Sr2Ca2Cu3 Oy(x = 0.0, 0.1, 0.2 and 0.3) have been studied by means of ultrasonic pulse transmission (UPT) technique at 1 MHz (300 K). The elastic moduli of the specimens are computed and corrected to zero porosity. The observed variation of elastic constants with aluminium substitution has been explained on the basis of the strength of interatomic bonding. The applicability of heterogeneous metal mixture rule for estimating elastic constants and transition temperature has been tested.
