ABSTRACT
To study the physical properties of biomaterials like bony hard tissues through the propagation of elastic waves is one of the most successful method.With the help of internal friction measurement, we can study the processes such as recrystallization, annealing, quenching and tempering, plastic deformation and strain ageing. In the present investigation we calculate and -1 reported the internal friction loss (Q ) for all the six types of bovine compact bones for the first time in a single experiment by using the ultrasonic piezoelectric composite oscillator technique with the help of X-cut crystal in different physiological conditions. Significant variation is observed from bone to bone. This may be attributed to composition and mineral content of the bones. Peak temperature data also is also determined. Temperature variation of logarithmic decrement in X-cut quartz transducer is also verified with mounting of bovine compact bar shaped bone -1 samples. Change of internal friction (Q ) with temperature is also calculated to predict the mechanism of acoustic losses and phase transitions in these bony hard tissues. Internal friction measurements are also useful to obtain the information about imperfections in bony hard tissues. The present investigation constitutes a step towards the application of natural bovine bone ceramic materials for the transducer applications
