摘要	Microstructural changes in Ti-5.6Al-4.8Sn-2.0Zr-1Mo-0.34Si-0.7Nd containing different amounts of carbon during solution treatment in the upper (alpha + beta) field have been investigated. It was observed that the (alpha + beta)/beta transus temperature increases rapidly in the carbon range 0-0-32 wt-% and exhibits a maximum at a content of 0-32 wt-%, while the alpha/(alpha+beta) transus temperature increases in a much less pronounced manner. For solution treatment in the high temperature (alpha + beta) phase field, carbon addition in the range 0 - 0.23 wt-% retards the change in volume fraction of the primary alpha phase with temperature. This makes it easier to adjust the volume fraction of the primary alpha phase through control of heat treatment temperature. Regression equations to predict the variation of volume fraction of primary alpha phase were obtained by multiple regression analysis. The experimental results are discussed in terms of phase composition analysis and the Ti - 8Al - C phase diagram.
