Creation of nanoporous metallic materials with laser influence application

Method of nanoporous structure's formation in model Cu-Zn alloy by force of component's with higher vapor pressure sublimation in vacuum is suggested. Give proof of reasonability implementation of preliminary laser treatment with diffractive optical elements application for creation fine-dispersed material structure. This treatment provisions increase pore's concentration and uniformly distribute them in volume. Implementation of metallographic and X-ray crystal analysis of material's porous samples are carried out. Changes of elements and fases structure in near-surface layer are fixed.
