     the objective of present work is to investigate the effect of macroscopic graphite particles on damping behavior of za-27 alloy composites. compo casting technique was used to prepare the composites, in which the graphite particles were used to reinforce za-27 alloy, in varying fractions in order to arrive at optimum graphite reinforcement for bearing applications and establish a correlation of experimental readings. the experimental method used was the cantilever technique with dynamic mechanical analyzer to evaluate damping properties. standard strips of size 60 mm × 10 mm × 1 mm thick were tested by cantilever method of vibration tests at various temperatures from ambient to 300 °c. it was observed that the damping capacity of the material increased with increasing temperature and fractions of graphite particles.
