Effect of annealing on nanostructure and magnetic properties of Zr2Co11 material
Single-phase Zr2Co11 nanomagnetic materials with high coercivity have been fabricated by melt spinning with subsequent annealing under Ar, N2, and vacuum. Annealing coarsens the grains and decreases the density of defects, leading to intergrain decoupling action and the enhancement of the magnetocrystalline anisotropy field of the hard magnetic phase. Therefore, coercivity increases 44.7% from ...
متن کاملSAED and HREM Studies of Zr2Co11 Intermetallic Compound
Rare-earth-free permanent-magnets have gained immense focus in the view point of mitigating the critical-material aspects of rare-earth elements. The intermetallic compound Zr2Co11 is a promising candidate. Polymorphism exists in the Zr2Co11 compound; a high-temperature phase has a rhombohedral structure and a low temperature phase has an orthorhombic structure [1,2]. Both of the two phases in ...
متن کاملA Comparison between the Effect of Cr and W Addition on Formation Kinetic of Nanostructure TiAl(γ) Alloy by Mechanical Alloying Route
In this research, mechanical alloying was used to produce Ti-50Al, Ti-45Al-5Cr and Ti-45Al-5W (at%) alloys. The effect of ternary addition (Cr and W) on microstructure and production efficiency of TiAl alloy were investigated. Alloying was performed in a planetary mill and the milling time varying from 5 to 70h. The structural evaluation in these powders was done by X-ray diffraction (XRD) tech...
متن کاملSynthesis of Nanostructure Ti-45Al-5Cr Alloy by Mechanical Alloying and Study the Effect of Cr Addition on Microstructure of TiAl Alloy
In this work, mechanical alloying was employed to produce Ti-50Al and Ti-45Al-5Cr (at%) alloys. Alloying was performed in a planetary mill and the alloying time varying from 5 to 70h. Characterization of the powder mixture was performed by X-ray diffraction (XRD), SEM analyses and DTA test, during mechanical alloying and after annealing at 1100°c in vacuum oven. The results showed, after 50h of...
متن کاملOptimization of micro hardness of nanostructure Cu-Cr-Zr alloys prepared by the mechanical alloying using artificial neural networks and genetic algorithm
Cu–Cr-Zr alloys had wide applications in engineering applications such as electrical and welding industrial especially for their high strength, high electrical as well as acceptable thermal conductivities and melting points. It was possible to prepare the nano-structure of these age hardenable alloys using mechanical alloying method as a cheap and mass production technique to prepare the non-eq...
