Abstract

In a multiphase composite, the particles of the "shallow" component (matrix, strengthening-phase particles depleted in oxide) will "wedge" between the "large" components, thereby reducing the value of the radius of their contact (especially for force SHS compaction - primary structure formation). When the concentration of the model particles of the "large" component of the strengthening corundum phase of the composite is less than the threshold, the "large" particles are isolated and the radius of the contact spot between them is zero: rk = 0. Upon reaching the threshold concentration (Xcr = Xpor), an infinite continuous sequence of contacting "large" (As in real SHS-metallokompozitah). In most types of armor after the Second World War, the face layer of cemented armor usually reached a hardness: less than -490, an average of -640 higher -700 Brinell units, the rear layer reached medium hardnesses of 220-240 Brinell. The hardness of homogeneous armor averaged 200-240 Brinell units, in some cases it dropped to 190. A similar ratio of hardnesses made it possible to realize the "spring effect", but, in our opinion, no more than 35-40%.
