Abstract

Ultrasonic field was applied to melted metal alloys during their solidification with the aim to obtain their microstructure in solid state characterized by small size grains. In the paper results of experimental re- search are presented obtained under application of an ultrasonic field of 100 - 350 W during the solidifica- tion of ATC Si10Cu4 alloy casted in a mould.
