The studies include the production of an amorphous alloy with the chemical composition Fe62Co9Y8W1B20 by two methods: injection and suction casting while maintaining similar production parameters (such as: chamber pressure, protective gas) and comparison of their structure and magnetic properties. The alloy was examined for structure by X-ray diffraction. The magnetic properties were determined on the basis of the VSM and the Faraday magnetic balance measurements. Solid amorphous iron-based materials are characterized by good magnetic properties. The influence of the method of production on these properties turns out to be significant, especially in the case of coercive field. The obtained results lead to further research on massive iron-based amorphous materials. Future research will address the effect of changes in the chemical composition of the alloy on magnetic properties and the continuation of studies on the impact of the manufacturing method on the structure and properties of alloys. The obtained alloy is characterized by good soft magnetic properties. It is possible to use it in electronics and electrotechnics, especially in devices where easy remagnetization of the material at specific frequencies is required.

ABSTRACTCurrent understanding of the local atomic structure of amorphous materials is reviewed. Sane results of probing short—range order by selected techniques are cited to illustrate the degree of uniformity that exists on a local scale. Observations of phase separation and phase changes are described with particular emphasis on a temperature driven, reversible transformation of the local structure observed magnetically in several cobalt—base glasses. The manifestations and implications of such transformations within the glassy state are examined. Several examples pointing to quasi—crystalline and to non—crystalline (non—space filling) local structures are given.

We have carried out magnetization and extended X-ray absorption fine structure measurements on an amorphous Gd68Cu32 ferromagent to investigate the relation between magnetic properties and the local structure in amorphous materials. Fluctuations in the exchange interaction for the ferromagnet are estimated experimentally within the framework of the nearest neighbor Heisenberg model.

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.

The Impact

We report on the synthesis and physical properties of cm-sized CoGeO3 single crystals grown in a high pressure mirror furnace at pressures of 80 bar. Direction dependent magnetic susceptibility measurements on our single crystals reveal highly anisotropic magnetic properties that we attribute to the impact of strong single ion anisotropy appearing in this system with TN∼33.5 K. Furthermore, we observe effective magnetic moments that are exceeding the spin only values of the Co ions, which reveals the presence of sizable orbital moments in CoGeO3.

In this paper, biaxial warp-knitted fabrics were produced with different high tenacity polyester linear density and inserted yarns density. The low-velocity impact property of flexible composites made of polyurethane as matrix and biaxial warp-knitted fabric as reinforcement has been investigated. The effect of impactor shape and initial impact energy on the impact response of flexible composite is tested. The results show that the initial impact energy have minor effect on the impact response of the biaxial warp-knitted flexible composites. The impact resistance of flexible composite specimen increases with the increase of high tenacity polyester linear density and inserted yarns density. The damage morphology of flexible composite materials is completely different under different impactor shapes. The findings have theoretical and practical significance for the applications of biaxial warp-knitted flexible composite.
