Abstract
It is presented some technological parameters and physical characteristics of Fe - Ni - Al composite materials, fabricated by pressing with following sintering at a high temperature, and also shock-wave compacted using explosives. The comparison of materials properties fabricated using different technologies at equal precursor powders parameters (dimensions and shape of particles, a way of their mixing and density of filling) points on the difference of their phase compositions, metallographic and defect structure, porosity and some physical properties.
