Abstract
- Equal channel angular pressing (ECAP) was performed on the extruded pure magnesium at 250°C for 4 passes. After ECAP processing, the grain size was significantly refined. And the damping capacity was increased at low strain amplitudes, but decreased at high strain amplitudes. Three peaks were observed during the measurement of damping capacity at elevated temperatures. The mechanisms for damping capacity of pure Mg at ambient and elevated temperatures were discussed.
