The research of intensification's expedients for nanoporous structures formation in metal materials by the selective laser sublimation of alloy's components

Intensification's expedients for nanoporous structures formation in metal materials by selective laser sublimation of alloy's components are researched. Processing of copper-zinc alloy L62 specimens by laser action with high impulse frequency is spent. Processing is spent in vacuum, the external stretching pres-sure have been enclosed to specimens with a surface received by mechanical polishing. The nanoporous structure with thickness up to 0.1 mm in brass L62 is formed as a result of laser action in vacuum. Pores are regularly distributed in the subgrain and sufficiently stable in sizes and form. Channel-type nanopores with width ~100 nanometers are formed on the border of subgrains, forming a porous network.
