Abstract:
To form nanoscale porous structures of solid crystalline materials it is proposed to use a sublimation method for more lighter-volatile components of a solid-solution type alloy in combination with laser radiation exposure with systematically variable spatial power distribution. Proper mechanical and physical properties of materials being treated are given by laser processing with the use of radiation focusators. The calculation is performed for radiation intensity distribution being formed by a focusator for laser processing that enables, for material postheating in a non-oxidizing media, to increase concentration of pores and to distribute them more homogeneously in a volume.

Key words:
