The regularities of material heating in the vicinity of nano- and micro-sized pores located near the surface of a metal sample subjected to ultrafast laser heating are theoretically considered. The model used the properties of a titanium alloy VT18u exposed to a laser pulse with a duration of 20 ns. The dependences of the material heating above and below the pore for different distances from the heated surface to the pore are established. It is shown that in the vicinity of the «ideal pore» a specific temperature distribution is formed with additional heating of the material over the pore in comparison with the defect-free material. It is shown that the most favorable conditions for pore healing are realized for small–diameter pores located at distance of 0.5 - 2 micrometers from the irradiated surface. Under conditions of simultaneous shock compression, this provides favorable conditions for filling the pore with heated material and its complete or partial healing.
