Effects Of Aging

The effects of aging treatment on the damping capacities of ZA84-xSb alloys were studied. The results show that in the aging treatment process, because of following mainly reasons: (1) the dissolution of the ternary phases, (2) the increase of grain interfaces, (3) the increases of dislocation density, and (4) the micro deformations of matrix interfaces and the second phases, the damping capacity of ZA84-xSb magnesium alloys did not be reduced. On the contrary, whether at the low temperatures or high temperatures, its damping capacity is higher than as-cast alloy, which is of great significance for the application of ZA84-xSb magnesium alloys.

Precision Test

The present situation of damping capacity for magnesium alloys test techniques and its equipment were reviewed. Because there were many types of test equipment, So it pointed out the suitability of all testing equipment and schemes for damping testing of magnesium alloys. And based on the research results of dislocation damping mechanism of magnesium alloys. The author holds that test scheme for torsional deformation of torsion pendulum and test scheme for bending and shearing deformation of dynamic thermal mechanical analyzer meet high-precision test requirements for non-linear damping capacity of magnesium alloys. The study make great value for testing damping of magnesium alloys and reflecting their damping advantage.
