Abstract

The elimination of LDI and HDI through dissolution and sinkage in TC4 Alloy during electron beam cold hearth melting was studied by adding artificial inclusion particles. The results show that a diffusion reaction exists between TiN and TC4 matrix at high temperature, which leads to TiN's dissolving in the titanium matrix in a certain duration. TiN particles with a size of 2.5 mm may dissolve completely in five minutes at the temperature of 1800°C. The artificial titanium sponge particles can float to the melt surface and dissolve in TC4 melt and WC particles can sink to the interface of the melt/skull, which is captured by the skull. LDI and HDI are eliminated through the mechanism of dissolution and floating by means of density difference during EB melting.
