Abstract

The article deals with ultrasonic testing possibilities of the copper alloy centrifugal casts. It focused on the problems that arise when testing

of castings is made of non-ferrous materials. Most common types of casting defects is dedicated in theoretical introduction of article.

Ultrasonic testing technique by conventional ultrasound system is described in the theoretical part too. Practical ultrasonic testing of

centrifugal copper alloy cast - brass is in experimental part. The experimental sample was part of centrifugally cast brass ring with

dimensions of Ø1200x34 mm. The influence of microstructure on ultrasonic attenuation and limitations in testing due to attenuation is

describes in experimental part. Conventional direct single element contact ultrasound probe with frequencies of 5 MHz, 3.5 MHz and 2

MHz were used for all experimental measurements. The results of experimental part of article are recommendations for selecting

equipment and accessories for casting testing made of non-ferrous metals.
