Abstract :
The longitudinal and shear wave velocities of titanium substituted magnesium ferrites were determined at room temperature by the pulse transmission technique. The values of Youngʹs modulus (E), and rigidity modulus (n) have been corrected to theoretical density. The elastic moduli are found to vary as cube root of the density. Further, a linear relationship between Debye temperature and average sound velocity has also been observed. The variation of elastic moduli and Debye temperature with increasing dopants concentration have been interpreted on the basis of microstructure of the samples.
