1. The effects of mass transferin the liquid phase on the rate of aluminium evaporation from the Ti-6Al-7Nb alloy

Author

L. Blacha, J. Mizera, and P. Folęga

Subjects
Ti-6Al-7Nb alloy, aluminium evaporation, VIM technology, mass transfer coefficient, Mining engineering. Metallurgy, TN1-997
Abstract

In the present paper, the rate of aluminium evaporation from the Ti-6Al-7Nb alloy during smelting with the use of VIM method at 5 to 1 000 Pa and 1 973 to 2 023 K has been discussed. It has been observed that pressure reduction and temperature rise affect aluminium elimination from the alloy. Based on the determined values of overall mass transfer coefficients and mass transfer coefficients in the liquid phase, it has been found that the resistance related to aluminium mass transfer in the liquid phase is about 8 % of the overall process resistance.

2. Loss of aluminium during the process of Ti-Al-V alloy smelting in a vacuum induction melting (VIM) furnace

Author

L. Blacha, G. Siwiec, and B. Oleksiak

Subjects
Ti-Al-V alloys, VIM technology, evaporation of Al, coefficient of evaporation, Mining engineering. Metallurgy, TN1-997
Abstract

In the present paper, results of the study on changes in basic Ti-6Al-4V alloy component contents during smelting in the vacuum induction melting (VIM) furnace are presented. The experiments were performed at 5 – 1 000 Pa and 1 973–2 023 K. Assuming that the observed loss of aluminium from the alloy during smelting is the effect of evaporation, an additional thermodynamic analysis was performed aimed at determining evaporation coefficients.
