Alloying effect on K X-ray intensity ratios, K X-ray production cross-sections and radiative Auger ratios in superalloys constitute from Al, Ni and Mo elements

Atomic spectrometry update-X-ray fluorescence spectrometry

“…53 The effect can be used for the quantitative determination of alloy composition. The influence of alloying effects was also reported by Aylikci et al 54 in research on the K-series peak ratios of Al, Mo, and Ni excited using 241 Am radioisotope source. Cengiz et al 55 studied the influence of chemical effects on the K-and L-series X-ray peak ratios in gold compounds.…”

Theoretical and experimental determination of K - and L -shell x-ray relaxation parameters in Ni

“…In fact, Han et al [11] have shown through this method that, in pure Ni metal, the evaluated occupation number of the 3d orbitals is 9.5218 while that of 4s or 4p orbitals is 0.4782, once again confirming a deviation from the ground state of isolated Ni atoms. Other FPs, such as fluorescence and CK yields, are also shown to be dependent on the chemical environment as, for example, in alloying, as shown by Aylikci et al in several works on transition metals [21,25,26]. In fact, in Krause's paper [4] …”

The Semi-Empirical Determination of K X-ray, KLL Auger Line and L subshell level widths for 3d transition elements at 59.5 keV

“…But the radiative K X-ray transitions can be affected by the outer shell electronic distributions. In our previous studies, it was obtained that K shell fluorescence yields did not change by the outer shell electronic distributions in energy dispersive x-ray fluorescence systems [22][23]. For the L subshell level widths determination, K line (originates from the transitions between L and K shell) widths are used in the literature [20] since these lines cannot be affected by outermost shell electronic distributions in 3d metals where the valence electrons are free to move throughout the metallic structure.…”
