Abstract

The effect of heat treatment on the damping properties of the Mn\|Cu damping alloy in extruding casting,compared with that in the water cooling permanent mold was studied.The results showed that under the condition of the 800 ℃×4 h solution treatment with immediate water quenching and aging at 400 ℃ for 4 h,the optimum damping property of MN\|Cu damping alloy in extruding casting that is higher by 20% than in water cooling permanent mold.Moreover,the damping property of the alloy changes with the frequency.A internal friction peak occurs at frequency 225 Hz.

Abstract

The effect of heat treatment on the damping properties of the Mn\|Cu damping alloy in extruding casting

compared with that in the water cooling permanent mold was studied.The results showed that under the condition of the 800 ℃×4 h solution treatment with immediate water quenching and aging at 400 ℃ for 4 h

the optimum damping property of MN\|Cu damping alloy in extruding casting that is higher by 20% than in water cooling permanent mold.Moreover

the damping property of the alloy changes with the frequency.A internal friction peak occurs at frequency 225 Hz.
