Damping Capacity of Aluminum 6061-Indium Alloys

Abstract

Monotectic Al-6061 alloys containing between 0 and 5.2 volume percent indium and pure indium samples were fabricated. Each sample was characterized by metallographic and analytical electron microscopy and the damping capacity and storage modulus were measured. The model proposed by L.G. Nielsen was used to calculate the damping capacity and storage modulus of the alloys using the damping capacity and storage modulus of the constituents. The damping capacity of the Al-6061-T6 alloy and increased with increasing indium content. The Nielsen model gave a good first approximation of the damping capacity and storage modulus of the alloys. Keywords: Damping; Modulus; 6061-Aluminum; Complex modulus.
