X-ray intensity ratios of various alloy compositions of Ti-Ni transition metal alloys have been investigated in this work using X-ray fluorescence spectroscopy. The spectrum of characteristic K-X-ray photons from pure Ti, pure Ni and Ti x Ni 1-x (x=0.30; 0.40; 0.50; 0.60; 0.70) alloys were detected with a high resolution Si (Li) solid-state detector. Firstly, K?/K? X-ray intensity ratios of pure Ti, pure Ni and Ti x Ni 1-x alloys were measured following excitation by 59.54 keV ?-rays from a 200 mCi 241 Am radioactive point source without any magnetic field and under 0.5 and 1 T external magnetic fields, separately. Later, the same measurements were repeated under the same experimental conditions for 22.69 keV X-rays from a 370 MBq 1 0 9 Cd radioactive point source. The results obtained for K?/K? X-ray intensity ratios of pure Ti, pure Ni, Ti and Ni in various Ti-Ni alloys were evaluated in terms of both external magnetic field effect and exciting photon energy effect. When the results obtained for both exciting photon energies are evaluated in terms of changing of K?/K? X-ray intensity ratios depending on the alloy composition, the tendency of these changes are observed to be similar. Also, K?/K? X-ray intensity ratios for all samples examined have changed with increasing external magnetic field. Therefore, the results obtained have shown that K?/K? X-ray intensity ratios of Ti and Ni in Ti x Ni 1?x alloys are connected with the external magnetic field. The present study makes it possible to perform reliable interpretation of experimental K?/K? X-ray intensity ratios for Ti, Ni and Ti x Ni 1?x alloys and can also provide quantitative information about the changes of the K?/K? X-ray intensity ratios of these metals with alloy composition. © 2016 Elsevier Ltdeninfo:eu-repo/semantics/closedAccessAlloyExternal magnetic fieldK?/K? x-ray intensity ratiosAlloyingFluorescence spectroscopyGamma raysMagnetic field effectsMagnetic fieldsMagnetismNickelPhotonsRadioactivitySemiconductor detectorsTransition metal alloysTransition metalsX ray spectroscopyAlloy compositionsExperimental conditionsExternal magnetic fieldHigh resolutionQuantitative informationSolid state detectorsX ray fluorescence spectroscopyX-ray intensity ratiosTitanium alloysnickelnitinoltitaniumArticlebiocompatibilitychemical analysischemical compositionconcentration (parameters)dosimetryexcitationmagnetic fieldmathematical computingphotonphysical chemistryphysical parametersphysical phasepriority journalradioactivityX ray fluorescenceAlloyExternal magnetic fieldK?/K? x-ray intensity ratiosAlloyingFluorescence spectroscopyGamma raysMagnetic field effectsMagnetic fieldsMagnetismNickelPhotonsRadioactivitySemiconductor detectorsTransition metal alloysTransition metalsX ray spectroscopyAlloy compositionsExperimental conditionsExternal magnetic fieldHigh resolutionQuantitative informationSolid state detectorsX ray fluorescence spectroscopyX-ray intensity ratiosTitanium alloysnickelnitinoltitaniumArticlebiocompatibilitychemical analysischemical compositionconcentration (parameters)dosimetryexcitationmagnetic fieldmathematical computingphotonphysical chemistryphysical parametersphysical phasepriority journalradioactivityX ray fluorescenceArticle11518318910.1016/j.apradiso.2016.06.026273950032-s2.0-84977663156Q3WOS:000382594900029Q3
