Abstract
The torsional vibration damping of mg-4.5 Ce alloys has been correlated with the texture orientation resulting from the method of fabrication. Forged and forged-plus-swaged alloys at vibratory stress levels of 1,500 psi exhibit specific damping capacities, respectively, of 6 and 11 times that of an extruded alloy of similar composition. Pole figures show that the basal planes are oriented preferentially in the extruded alloys with a 20 degree tilt to the axis of the extrusion, while the basal planes are generally parallel to the rod axis for forged or forged-plus-swaged alloys. The correlations indicate that the major source of damping in these hexagonal magnesium alloys is stress-induced anelastic shear on the basal planes (probably by dislocation motion).
