Abstract
A nanoscale composite of alpha-Ti and Ti3Si phases as been produced by annealing the as-quenched amorphous Ti80Si20 alloy containing 0.6 wt% Nd. Detailed electron microscopic studies of the crystallization beha vior of the amorphous alloy established that very fine particles of al pha-Ti form first, followed by the precipitation of the predominant be tetragonal Ti,Si and a small amount of Ti5Si3 compounds. Ultrafine al pha-Ti crystallites are observed only inside the Ti3Si phase. The form ation and microstructural characterization of the Ti3Si phase are also presented.
