Characterization of the Interface Between α and β Titanium Alloys in the Diffusion Couple

The aim of the research was to investigate the microstructural changes caused by diffusion through interface between α and β titanium solid solutions. For this purpose, a diffusion couple composed of two single-phase titanium alloys— α type commercially pure (CP) titanium Grade 2 and near- β Ti-15V-3Al-3Cr-3Sn—was made by annealing at a temperature of 850 °C in an inert atmosphere. The performed heat treatment caused partial diffusion bonding...
