Strength and conductivity ofin situ Cu-Fe alloys

Journal of Materials Science, 1989
Alloys of Cu-Fe with iron contents from 10 to 30 wt % have been prepared by casting plus mechanical reduction. A series of heat treatments was done at various stages of the mechanical reduction to promote precipitation of the iron from the copper matrix with the hope of optimizing electrical conductivity at a given strength level.

The Mossbauer spectrum model of Cu-Fe alloys

Journal of Physics F: Metal Physics, 1982
The Mossbauer spectrum model was proposed in order to obtain a better understanding of the iron atom 'states' in a supersaturated Cu-Fe solid solution and their changes during the gamma Fe precipitation process and growth of this phase. The model is related to the atomic structure of this alloy.

Mechanical Milling of Quasicrystalline Al-Cu-Fe Alloys

Materials Science Forum, 2014
Ingots of alloys Al-Cu-Fe were obtained by casting in a graphite mold. Mechanical milling of alloy particles in the as-cast state and after homogenization annealing was carried out in planetary ball mill Retsch PM400 in an argon atmosphere. As a result of mechanical milling granules with an average size of 35-40 μm and fine internal microstructure are ...

Spin glass of liquid-quenched Cu-Fe alloys

Journal of Magnetism and Magnetic Materials, 1986
Abstract The spin glass state of the liquid-quenched Cu-Fe alloys up to 9% Fe with fcc structure has been investigated by means of magnetic susceptibility, electrical resistivity and Mossbauer spectrum measurements. Change of the spin glass nature by annealing was observed and the clustering effect of Fe atoms was made clear.

Laser Surface Alloying of Aluminium Alloys with Cu/Fe Metallic Powders

Solid State Phenomena, 2020
In this paper, the influence of laser surface alloying on the structure and mechanical properties of aluminium alloy was analysed. As a parent material aluminium EN AC-51300 alloy was applied. The laser surface alloying was executed by direct introduction of metallic powder Fe/Cu into the remelted area (molten pool).

Mechanical alloying of Al–Cu–Fe elemental powders

Materials Science and Engineering: A, 2001
Abstract The formation of quasicrystalline powders by mechanical alloying of crystalline elemental powders has been investigated for Al 70− x (Cu,Fe) 30+ x ( x =0, 5, 7) alloy systems. The alloying process during milling and additional annealing at elevated temperature has been characterized by X-ray diffraction and transmission electron ...

Magnetic impurity pairs in dilute Cu(Fe) alloys

Physics Letters A, 1971
Abstract Further analysis of our measurements of the magnetization of dilute Cu(Fe) alloys reveals new results which reinforce our interpretation of those data in terms of the fundamental behavior of impurity pairs.

Irradiation-induced patterning in dilute Cu–Fe alloys

Journal of Nuclear Materials, 2014
Abstract Compositional patterning in dilute Cu 1− x Fe x ( x  ≈ 12%) induced by 1.8 MeV Kr + irradiation was studied as a function of temperature using atom probe tomography. Irradiation near room temperature led to homogenization of the sample, whereas irradiation at 300 °C and above led to precipitation and macroscopic coarsening.

Deformation Characteristics of Quasicrystalline Al–Cu–Fe Alloys

Journal of Materials Research, 1997
The deformation characteristics of icosahedral Al–Cu–Fe quasicrystals were determined by high temperature creep experiments between 680 and 720 °C and 15 and 41 MPa. The deformation process was determined to be controlled by grain boundary mechanisms.
