Present Status of Damping Test Techniques for Magnesium Alloys

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.
