Sažetak

This article proposes to use the coherence function in structural examination of saturated composite castings, widely used in the maritime industry and the construction of machines and vehicles. These castings are characterized by a complex structure due to the presence of a tough reinforcement phase in a matrix, mostly an alloy made of light metals. Such combination generates a number of defects, particularly in composite materials made by casting. Elimination of the defects, preceded by immediate detection, preferably through non-destructive tests, may contribute to reducing operating costs.
