Microstructure Analysis of Equiatomic Multi-Component NI20TI20TA20CO20CU20 Alloy

MICROSTRUCTURE ANALYSIS OF EQUIATOMIC MULTI-COMPONENT Ni 20 Ti 20 Ta 20 Co 20 Cu 20 ALLOYAn equiatomic multi-component alloy Ni 20 Ti 20 Ta 20 Co 20 Cu 20 (at.%) was obtained using vacuum arc melting.In order to characterize such an alloy, microstructure analysis has been performed using Scanning and Transmission Electron Microscopy, Electron Backscattered Diffraction, X-ray Diffraction and Energy Dispersive X-ray Spectroscopy techniques.Microstructure analysis revealed the presence of one rhombohedral and two cubic phases.Energy Dispersive X-ray Spectroscopy measurements revealed that both observed phases include five chemical elements in the structure.Using Rietveld refinement approach the lattice parameters were refined for the observed phases.
