Dependencies of Young"s modulus and fluctuations decrement in powder Titanium sintered under temperatures of 773—1473 К from porosity are studied. Fluctuations decrement of material with perfect contact between particles is established to be of the order of this value of molten Titanium and doesn”t depends on porosity. The source of the energy dissipation increase is in imperfect contacts. The apparent dependency of damping capability from porosity points on increase in imperfect contacts content in incompletely sintered Titanium during the increase of porosity.
