The effects of cold rolling process and annealing treatment on damping properties of 3105 aluminum alloy

Abstract

The effects of cold rolling and annealing treatment on damping properties of 3105 aluminium alloy was studied. The aluminium alloy have deformed by cold rolling process to 50 percent, 60 percent, and 70 percent rolling reduction. In order to reduce the strain hardening of the samples, an annealing treatment was performed after cold worked process. The lower the rolling reduction, the higher the damping capacity of the sample. The sample for 50 percent rolling reduction before annealed has increase in damping capacity from 0.0361 to 0.1318. When the samples undergo two different annealing temperature and soaking hours, the damping properties such as loss modulus, storage modulus, and damping capacity show some changes in trend curves and experimental value. The damping capacity for sample 50 percent rolling reduction and after annealed at temperature 300 °C for one hour was increased from 0.0193 to 0.1405 at temperature 50 °C to 380 °C.
