Investigation of alloying effects on XRF parameters of 3d transition metals in Permendur49, Kovar and Ti50Co50 alloys

Abstract

The alloying effects on X-ray fluorescence (XRF) parameters such as K shell fluorescence cross-sections (s Ka , s Kb and s K ), K shell average fluorescence yields (u K ) and K to L shell vacancy transfer probabilities (h KL ) of V, Ti, Fe, Co and Ni 3d transition metals in Permendur49 (Fe 49 Co 49 V 2 ), Kovar (Fe 54 Ni 29 Co 17 ) and Ti 50 Co 50 alloys have been carried out by X-ray fluorescence studies. K X-ray intensity ratios of these 3d transition metals in both pure form and present alloys have been measured following excitation by 22.69 keV X-rays from a 10 mCi 109 Cd radioactive point source. The characteristic K-X-ray spectra from samples were detected by a high-resolution Si(Li) solid-state detector. The investigated fluorescence parameters of present 3d transition elements in alloys indicate significant differences with respect to the pure metals. Consequently, the observed change of the investigated fluorescence parameters can be attributed to the delocalization and charge transfer phenomena between the 3d elements in alloys.

Spectroscopic Characterization of Some Foil Alloys Based on Nickel

“…In this way, alloys can be used to reduce cost of material by preserving or changing some important properties, which is the reason why they have been used in a wide variety of applications [1]. Therefore, in many studies, alloys with different contents and preparation methods have taken part in previous studies [1][2][3][4]. A magnetic alloy is an integration of various metals that contains at least one of the three main magnetic elements: iron (Fe), nickel (Ni), or cobalt (Co).…”
