Microstructure of Multi-Component Ni35Ti35Ta10Co10Cu10 Alloy

A new NiTi-based multi-component Ni₃₅ Ti₃₅ Ta₁₀ Co₁₀ Cu₁₀ (at.%) alloy was obtained by vacuum arc melting. The microstructure of the alloy has been studied using scanning and transmission electron microscopy, backscatter electron diffraction and X-ray diffraction techniques. The performed measurements showed presence of two cubic and one tetragonal phases. Energy dispersive X-ray spectroscopy analysis confirmed that all the observed phases contained all five principal elements.
