Estimation of level of internal pressure in near$surface a layer nanoporous the metal materials

The investigation of internal stress level in near surface layer of nanoporous metal materials, received by the method of selective laser sublimation, is executed. Researches of copper zinc alloy specimens were spent with use of diffractometer DR 01 «Radian». It is established that as a result of selective laser sublimation in near surface nanoporous layer relative internal stress about 11·10 3 is formed, that at investigation of main temper for planar stressed state condition corresponds to value σ = 2,8 GPa.
