摘要：

Wavelength-dispersive electron probe microanalysis (WDS-EPMA) of TiN/Ti diffusion couples was carried out in order to determine the nitrogen profiles across the phase bands. The in situ TiN/Ti diffusion couples were used for phase equilibrium studies. The problem of complete overlap of the Ti(L1) and N(K-alpha) lines was solved using chemically well-characterized single-phase titanium nitride samples (alpha-Ti(N), epsilon-Ti2N and delta-TiN1-x) as external standards. By using such homotypic standard materials it was possible to eliminate systematic errors introduced by imperfect correction algorithms. The composition of the phases in multiphase TiN/Ti diffusion couples could be determined with an accuracy of better than +/- 1 at% N.
