X-Ray-Line-Profile Analysis of Titanium Alloys

Abstract

X-ray-line-profile analysis has been used to investigate the dislocation structures resulting from severe plastic deformation in a series of titanium alloys. The effect of oxygen level (up to 0.33 wt-%) on the dislocation arrangements in titanium as well as in a series of titanium-aluminum alloys (4, 6, and 9 wt-% Al) was the principal thrust of the investigation. Four commercial alpha-phase titanium alloys (Ti-7Al-2Cb-1Ta, Ti-5Al-2.5Sn, Ti-7Al-12Zr, and Ti-4Al-3Mo-1V) were also examined. Although correlations were found between the stacking fault probability and alloying elements, the dislocation arrangements can not be interpreted solely in terms of stacking fault energies. Short-range order definitely plays an important role, and solute-dislocation interactions may be active.
