Near equiatomic FeCo alloys: Constitution, mechanical and magnetic properties

Epitaxially stabilized TiN/(Ti,Fe,Co)N multilayer thin films in (pseudo-)fcc crystal structure by sequential magnetron sputter deposition

“…In particular, no amorphous regions are obtained in any of the TiN films in all cases. A dependency of the multilayer thin films' microstructure on the bilayer period can be observed: The diffraction pattern obtained from the film with Λ = 449 nm exhibits the (111) and (200) reflections of TiN in the NaCl tape crystal structure as well as the (110) reflection of FeCo in the CsCl type crystal structure which are the stable phases of the respective binary material at standard conditions [11]. When the bilayer period is reduced to values below 449 nm the FeCo(110) reflection vanishes which indicates a decrease in the grain size in the FeCo phase.…”

Thermodynamic properties of dilute Co-Fe solid solutions studied by 57Fe Mössbauer spectroscopy

“…As a result of all of the above Co-Fe alloys are attractive materials for many applications, even at elevated temperatures. In particular, these alloys are used in the production of turbine engine components, transformers, magnetic bearings and recording heads [1][2][3][4][5]. At the same time, this system is regarded as a model for experimental and theoretical studies of thermodynamic properties [6][7][8].…”

Oxidation Resistance of Nanocrystalline Alloys

“…Consequently, nanocrystalline materials exhibit properties that are significantly different from and often improved over, their conventional microcrystalline (mc) counterparts. For example, nanocrystalline materials exhibit increased mechanical strength [6][7][8][9][10], enhanced diffusivity [11], improved corrosion resistance (some nanocrystalline materials) [12][13][14][15][16][17][18][19][20], optical, electrical and magnetic properties [21][22][23][24]. Due to their unique properties, nanocrystalline materials have attracted considerable research interests and the field of nanocrystalline materials has now become one of major identifiable activities in materials science and engineering.…”
