Abstract

Benchmark X-ray diffraction intensities for α- and β-phases in titanium alloys have been improved with the help of polycrystalline samples of α-alloy VT1-0 and β-alloy Ti–3Al–7Mo–5,5Cr (% wt.). In order to achieve statistically significant data for each sample the corresponding X-ray diffraction patterns have been obtained in four different non-orthogonal macroplanes. Theoretical calculation of specific integral diffraction intensities for h.c.p. and f.c.c. lattices of α- and β-phases has been accomplished in accordance with kinematic theory. As a result a number of averaged normalized diffraction intensities for α- and β-phases have been obtained, the intensities being suitable for direct use in quantitative phase and texture analysis of various titanium alloys.
