Abstract
The results of experimental and theoretical investigations of the structural sensitivity of the elastic modulus of powders biporous nickel are reported. The previously proposed theoretical dependence of the elastic modulus of a biporous system on structural parameters has been verified. It is shown that the elastic characteristics of biporous materials can be varied over a wide range if the parameters θmicr θmacr and λ (the particle size ratio of the pore-forming agent and the powder) are varied. The values of those parameters to some degree also affect the mechanical behavior of biporous nickel near the porosity limit θc. If λ and θmacr/θmicr increase while the integrated porosity remains constant the elastic modulus and the porosity limit rise.
