Definition of the apparent elastic limit's change in metal materials at nanoporous structures formation

In the propulsion engineering application of metal materials with nanoporous surface is perspective for rising antifrictional properties of tribological units and interacting surfaces conformability. The method of formation nanoporous structures in metal materials by laser influence is developed. Similar structures could also be received by vacuum isothermal soaking of binary alloys, in this case accumulation of separate and tunnel pores occurs with smaller speed. Dependence of material apparent elastic limit's change on duration of high-temperature influence in vacuum is defined.
