An Investigation of the Damping Properties of VACROSIL-010

Abstract

The strain dependence and specific damping capacity (SDC) of the damping alloy, Vacrosil-010 (84.5 Fe, 11.3 Cr, 2.4 Mo), was determined using a modified version of the resonant dwell technique. Cantilever beam specimens were annealed for 1 hour at temperatures between 800 C and 1100 C. They were subsequently vibrated at their first three resonant modes ( 0-1000 Hz) at room temperature. The effect on damping capacity of changes in heat treatment were investigated using tensile hysteresis testing, optical microscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM).
