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 ...

task-based instruction, consciousness-raising and iranian efl learners acquisition and use of collocation

the present study sought to examine whether a task-based approach could have an impact on raising awareness of collocations. moreover, it sought to investigate the facilitative role of consciousness-raising tasks of collocations in the communicative instances of use. to this end, 68 intermediate learners of english were selected via a placement test. the participants were taught with classroom ...

Structural Phase Transformation and Phonon Softening in Iron-Based Alloys

The interrelation of Invar and Martensite in iron-based alloys like Fe3Ni is discussed on the basis of ab initio calculations for different crystal structures. Inelastic neutron scattering and ultrasonic experiments have shown that a soft transverse phonon mode in [110] direction acts as a precursor in the close packed fcc phase of these systems. Unfortunately there are no experimental results ...

Annealing temperature effect on nanostructure and phase transition of Copper Oxide thin films

This paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by PVD method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°C) with a flow of 1 cm3s-1 Oxygen. The X-ray diffraction (XRD) was employed for crystallographic and phase analyses, while atomic force m...
