Abstract: The present study aims to understand the effect of Si and Ge addition on the evolution of microstructure in near alpha titanium alloys. An alloy of nominal composition Ti-5Al-2Sn-4Zr-2Mo with different amount of Si and Ge were prepared. Owing to the different processing conditions, precipitates were of wide size distribution. They formed mostly at grain boundaries, few at grain interior as well. Precipitates were of either Ti5Si3 or Ti5Ge3 type with large variation in the solute content, suggesting that they are off-stoichiometric. Precipitate morphology varied from fine equi-axed to large, elongated shape with planar interface. Both Si and Ge have a substantial influence on the evolution of grain size. Transmission electron microscope investigation of alloys displayed prominent occurrence of widely spaced intense slip in the hot rolled material. © (2014) Trans Tech Publications, Switzerland.
