It is shown that the dimensions, number, shape of the pores may be controlled of depending on thermodynamic parameters. It is revealed that either ordered or disordered structures may be formed in Gasars. The conditions of pore nucleation and gas-eutectic cooperative growth are considered. It is shown that gas-eutectic reaction similar eutectic but has it own differences. Mechanical and physical properties of gas-eutectic materials - gasar - are investigated. It is revealed that as other eutectic materials gasars have superiorities in strength and plasticity due to ordered orientation of crystal and gaseous phases.
