Changes in the Structure and Properties of Single- and Multilayer Materials Under the Influence of the High-Velocity Stream of Microparticles
This chapter is dedicated to the results of the theoretical and experimental researches of the alteration processes of the structure and properties of metals (steel, aluminum, titanium) and single- and multilayer protective materials under influence of microparticles. A peculiarity of the impact-wave processes in the crystal structures is a very rapid (for the time of 10−11 − 10−12s) pressure build-up as per the front of the shock wave, which creates great deformations in the surface layer of an obstacle and results in crushing grains of metals into tinier crystallites. Also, here will be analyzed in depth measurements of the volt-ampere characteristics of the “unprotected” integrated circuits (ICs) of mass production as compared with the test results of the analogous parameters of integrated circuits, structurally designed in the special packages from these composite protective materials.
