Spin fluctuations in an amorphous alloy

Physical Review B, 1996
Enhancement of the effective electron mass by spin fluctuations (SF's) has been studied in a-${\mathrm{Fe}}_{\mathit{x}}$${\mathrm{Zr}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ (27%\ensuremath{\leqslant}x\ensuremath{\leqslant}39%) by low-temperature calorimetry.

Structure of amorphous metallic alloys and the conditions of amorphization

Metal Science and Heat Treatment, 2000
The results of x-ray study of amorphous metal alloys are compared with the structural parameters of intermediate phases determined for equilibrium state diagrams and primary products of crystallization upon warming of amorphous alloys and crystal phases (formed at “subcritical” cooling rates) of the alloys susceptible to amorphization. It is found that

Bending of amorphous alloys

Journal of Materials Processing Technology, 1992
Abstract Fe-based and Ni-based amorphous foils with thicknesses of 25–30 μm have been used for bending experiments. First, the mechanical and physical properties of the foils were measured, after which bending experiments were carried out by four bending methods, i.e., conventional V-bending, L-bending with a lateral force, multi-stage V-bending and ...

Amorphous metallic alloys

Uspekhi Fizicheskih Nauk, 1990
The experimental data on the structure of and the structural defects and structural relaxation in amorphous metallic alloys are reviewed. The elastic and inelastic properties of amorphous metallic alloys and the effect of disorder in the arrangement of atoms on the ferromagnetic properties of amorphous metallic alloys are also studied.

Amorphization by mechanical alloying

Journal of Non-Crystalline Solids, 1990
The solid state amorphization methods of mechanical alloying (MA) of mixtures of elemental powders and mechanical milling (MM) of single component powder (intermetallic compound or element) are discussed. The mechanism for amorphization by MA is probably a variation of amorphization by interdiffusion of thin film diffusion couples with the added ...

Diffusion in amorphous alloys

Scripta Metallurgica, 1980
This paper describes how atomic diffusion coefficients in amorphous alloys are affected by temperature, the nature of the diffusing atoms, and the amorphous alloy structure, composition, and heat treatment. Amorphous alloy diffusion is shown to obey Arrhenius and normalised Arrhenius laws, and in general to be faster than vacancy controlled diffusion ...

Fretting of Amorphous Alloys

MRS Proceedings, 1981
ABSTRACTAmorphous surface layers produced by bonding metglas ribbons onto steel specimens were tested for their resistance to fretting. Friction and weight loss were determined and the worn surfaces were examined optically. There was no general tendency towards a better wear resistance of the tested amorphous metals as compared to crystallized metals ...

Magnetism in Amorphous Alloys

AIP Conference Proceedings, 1976
The present state of knowledge and understanding of the basic magnetic properties of amorphous alloys is reviewed. It covers magnetic moments, exchange interaction, temperature dependence of the magnetization and anisotropy for two categories: metal‐metalloid and rare earth‐transition metal amorphous alloys.
