This work is devoted to grain refinement of the foundry Al-20 wt% Zn (AlZn20) alloy, aiming at improving ductility of the sand-cast alloy The melted alloy was inoculated using traditional AlTi5B1 (TiBAl) and AlTi3C0.15 (TiCAl) master alloys and newly introduced (Zn,Al)-Ti3 one. The performed structural examinations showed out significant increasing of the grain population of the inoculated alloy and plasticity increase represented by elongation. The high damping properties of the initial alloy, measured using an ultrasonic Olympus Epoch XT device, are basicly preserved after inoculation. Also tensile strength preserves its good values, while elongation shows an increase-which are beneficials of the employed grain-refining process.
