Abstract
The article presents the results of studies elastic-fluid properties of metal-composite materials such as ALOR and SIAL. Modulus of elasticity in the range 55,5 1010 - 7,2 1010 Pa, Poisson's ratio of 0.24 - 0.35, the logarithmic decrement of oscillations does not exceed 5%, and studies have shown that practically do not depend on the level of loading in the investigated range of relative strain (ε = 50 10-5 – 200 10-5), while for alloy D16 decrement does not exceed 0.6%.
