Abstract: Relief annealing technique of 304 Metal Rubber is researched. Test results show that relief annealing can significantly change the static loss factor and the dynamic loss factor of 304 Metal Rubber. It is found that the influences of annealing temperature, annealing time, Metal Rubber density and cooling manner on the static loss factor and the dynamic loss factor are obviously different. The optimal combination of the relief annealing parameters of 304 Metal Rubber is: annealing temperature 270 ℃, annealing time 25 minutes, Metal Rubber density 1.6 g/cm3, and oil cooling manner.
