Damping properties of porous titanium and pseudoalloys based on it

The vibration-absorbing capacity of titanium increases with an increase in porosity, which is the resuit of the higher stress concentration at the surface of pores causing a higher level of microplastic deformation in the local areas of the skeleton. The size of the titanium powder fraction has a significant influence on the vibration-absorbing properties of the investigated materials. An increase in the titanium powder size causes easing of the conditions for occurrence of local deformations in the larger microvolumes.
