Damping Capacity and Mechanical Properties of Sintered Fe—Cr—Mo High-Damping Alloys

Pages 205-211 | Published online: 19 Jul 2013
 

Abstract

The damping capacity and mechanical properties of ferromagnetic porous sintered specimens having a composition within the range iron plus 0–16%Cr and 0–4%Mo have been examined. Damping capacity and the mechanism of damping are discussed with respect to the effect of porosity and the stress concentration around each pore under the influence of an applied vibrational stress. Maximum damping capacity was obtained with a composition of Fe–16Cr–2%Mo, vacuum-sintered at 1200°C for 120 min at a pressure of 2·66 Pa (2 × 10−5 torr).
