Tin bronzes have found wide application in various branches of industry to fabricate parts operating under the friction conditions. For example, the distribution of the eutectoid component is regulated for bronze BrO10C2N3 when producing important parts. In this study, the influence of ingot casting and solidification conditions on the distribution and amount of eutectoid in the alloy structure is investigated. Several types of bronze casting into the water-cooled and uncooled mold, as well as when applying ultrasonic waves and without them, are tried out. These trials result in the development of casting tin bronze BrO10C2N3 into a combined casting mold situated in the ultrasonic field. The mold itself is a steel mold placed into a graphite filler with a heat-insulating insertion in the upper mold part. The results show that the application of a new technology make it possible to fabricate ingots in complete correspondence with requirements of the normative documentation and a high product yield over 70%. © 2016, Allerton Press, Inc.
