Sažetak

Savremene legure na bazi nikla i titanijuma, sa većim brojem novih elemenata, imaju široku primenu. Tako dobijene nove legure titanijuma su od velikog praktičnog značaja u vazduhoplovstvu, a novodobijene legure nikla u energetici i nuklearnoj tehnici. U okviru ovog rada su prikazani rezultati tretiranja legura titanijuma i nikla snopovima lasera u vazduhu, na atmosferskom pritisku, kao i pojedinih uzoraka u vakumskim uslovima. Dobijene laserske modifikacije mikrostruktura uzoraka su analizirane različitim metodama ispitivanja, koje uključuju optičku i elektronsku mikroskopiju (SEM). Savremenim numeričkim metodama je, za izabrane režime rada lasera, simulirano grejanje do tačke topljenja odgovarajućeg materijala.
