Abstract

The foundry characteristics of the VTI-4 intermetallic alloy have been determined for a vacuum arc furnace with a centrifugal casting of the melt into ceramic or metallic forms. It has been found that the VTI-4 intermetallic alloy has low casting characteristics in comparison with the VT5L alloy and Ti–16Al intermetallic alloy (mass. %): 40% more shrinkage, 44% less fluidity and 26–28% less fillability of the mold. The obtained casting characteristics of VTI-4 alloy can be used to develop an experimental foundry technology for the production of parts from it. The obtained casting characteristics of VTI-4 alloy can be used to develop an experimental foundry technology for the production of parts from it сomplex direction 7.1. «Intermetallic titanium alloys» («The strategic directions of development of materials and technologies of their processing for the period till 2030») [1].
