Ways to eliminate the influence of the chemical composition of nickel alloys on the results of spectral analysis

Nonferrous Metallurgy - II. Zirconium, Hafnium, Vanadium, Niobium, Tantalum, Chromium, Molybdenum, and Tungsten

“…A new method for the preparation of standards for the spect,rographic analysis of alloys was suggested (54). Electric excitation methods were compared with laser excitation and the latter type of excitation was found to give less reproducible results but the third element effect on calibration curves was eliminated (493). Laser microspectroscopy was also used to determine Cr semiquantitatively in oxidic and metallic surfaces (594).…”
