Bi1.7Pb0.3AgxSr2Ca2 Cu3Oy (x = 0.0, 0.1, 0.2, 0.3 and 0.4) superconducting samples have been synthesized by the matrix method. From X-ray diffraction and d.c. electrical resistivity results, it has been confirmed that silver doping does not poison the superconductivity and Tc (0) varied between 95 K and 105 K. The ultrasonic compressional (V1) and shear (VS) velocities at room temperature were determined for all the samples by the ultrasonic pulse transmission technique. The Young's modulus and rigidity modulus values were calculated and were found to decrease with increasing silver doping. Microhardness measurements were performed using the indentation method. The hardness decreased with increase in lead concentration and further decreased with addition of silver. The hardness values were calculated for all the samples from the elastic data and these values are in good agreement with the experimental data.
