The aim of the carried out studies was to establish in what degree X-ray radiography is useful for finding defects in metal-matrix composite materials. These materials have various defects due to their specific composition. Especially when we take composites produced with casting methods into consideration. An effort to establish a degree of the influence of the phenomenon of electromagnetic diffusion on the boundary of matrix/ reinforcement phases was made in the results analysis of the studies.Rabjenje radiografije x-zrakama u pronalaženju grešaka lijevanih kompozita metalne matrice. Cilj članka je utvrđivanje u kojoj razini primjenjiva je radiografija x-zrakama u pronalaženju grešaka lijevanih ompozita metalne matrice. Ovi materijali imaju različite greške glede njihovog specifičnog sastava. Posebice kada se motre kompoziti dobiveni ljevanjem. Skrb utvrditistupanj utjecaja fenomena elektromagnetne difuzije na granice matrica-ojačane faze, daje se kao rezultat ove analize u članku
