Application of Spectroscopic Methods for Analysis of Ni-Based Alloys (Ni% ≥70)

Abstract

In this paper, we investigate the structural and magnetic properties of Ni based alloys which are in the form of NixFeyMoz (x = 0.80; y = 0.15; z = 0.05), NixCryFez (x = 0.70; y = 0.20; z = 0.10), and NixCryAlzCut (x = 0.75; y = 0.20; z = 0.025; t = 0.025) and are prepared by heating the pellet formed samples at high temperature. For this purpose, electron paramagnetic resonance experiment is performed for analysis of paramagnetic centers of these compositions to see the behaviours of alloys in an external magnetic field. g values are calculated from electron paramagnetic resonance spectra recorded at room temperature. Structural features of NixFeyMoz, NixCryFez and NixCryAlzCut alloys are observed by x-ray diffraction technique. Line positions and line intensities are discussed by the help of x-ray diffraction spectra recorded at room temperature. In order to understand the surface morphology of samples, scanning electron microscopy; for the elemental compositions of the alloys energy dispersive spectrosopy experiments are carried out at room temperature.

Evaluation of radiation shielding potentials of Ni-based alloys, Inconel-617 and Incoloy-800HT, candidates for high temperature applications especially for nuclear reactors, by EpiXS and Phy-X/PSD codes

“…Many studies about alloys for different purposes were reported before [6][7][8][9][10][11][12][13][14]. Among the alloys, Ni-based alloys, Inconel-617 and Incoloy-800HT, were also studied by many researchers previously [1,4,[15][16][17][18][19][20].…”

Spectroscopic Characterization of Some Foil Alloys Based on Nickel

“…The nickel-based alloys containing about 79% Ni have high initial and maximum permeabilities and very low hysteresis losses. Additions of 4-5% Mo, copper or chromium to 79% Ni-Fe alloy, have made the alloy interesting and the magnetic characteristics of the structures important [2]. * Corresponding Author: zeynepyarbasi@hotmail.com In this work, our aim is to study the nickel-based foil alloys, which have diverse considerable features and various applications.…”

“…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).…”
