The results of DC Cu-Al2O3, Cu-SiO2, Cu-W, and Ni-ZrO2 structure exploration show that the objects in initial state being characterized by the fine-grained metal base (grain size ~ 0,2-1,5 mkm) with the high-dispersed particles (particle size 3-20 nm) of strengthened phase. The high DC structure stability at high-temperature heats causes the stability of their high-strength state. There are determined that the DC flow stress at the elastic limit being controlled by additive contribution of grain boundary and orovan strengthening. The correlation between them depends on undercoat temperature and volume part of strengthened particles. The regularities of DC deformation strengthening and plasticity were studied. There are shown that the lowering of DC deformation strengtheni ng velocity depending on deformation degree logarithm having the stage character. The final stage of strength is the steady-state deformation, or stage without strength, for most of research systems. The temps of objects plasticity decrease at the structure parameters dispersity and volume part of strengthened phase increase were analyzed. The technological recommendations were proposed and the conditions of realization the high construction strength in condensed DC were formulated at the base of correlation regularity compare structure with the strength and plasticity characteristics.
