The presented research work contains the results of investigations concerning the stereological aspects of damping capacity in tool steel. The Forster's elastomat was used to determine the damping characteristics. Basing on the quantitative metallographic method, the effect of carbide banding on vibration damping capacity of steel submitted to the forging process has been determined. As the result, the regression between the logarithmic decrement of vibrations and estimator of surface area carbide-matrix has been obtained. The carbide size limit above which the carbide particles affect significantly the vibration damping phenomenon has been determined too.
