摘要
The present work highlights the build up of the microsegregation coming from both solidification and high temperature solid state transformation in Ti-46Al-8Nb (at.%) alloy prepared by quench during directional solidification (QDS) experiments. Microstructure analysis of the QDS samples associated with quantitative chemical analysis were performed and compared to as-cast structures and heterogeneities. It is found that the microsegregation formed during solidification favours the beta -> alpha solid state transformation at higher temperatures and thus intensifies the solid state segregation.
