Hard magnetic bulk amorphous alloys
IEEE Transactions on Magnetics, 1997An amorphous phase in Ln-Fe-Al (Ln=Nd and Pr) systems is formed in wide composition ranges of 0 to 90 at% Fe and 0 to 93 at% Al by melt spinning. Ferromagnetic Ln/sub 90-x/Fe/sub x/Al/sub 10/ bulk amorphous alloys with high coercive force (/sub i/H/sub c/) at room temperature are obtained by copper mold casting.

Superconductivity in amorphous actinide alloys
Physical Review B, 1985Superconductivity has been studied in amorphous binary alloys of actinides containing Co, Fe, and Ni. Amorphous thorium alloys have critical temperatures of up to 3.8 K and electronic properties similar to other transition-metal amorphous alloys. By contrast, amorphous uranium alloys have critical temperatures below 1.0 K and exhibit two unusual ...

Ferromagnetic bulk amorphous alloys
Metallurgical and Materials Transactions A, 1998This article reviews our recent results on the development of ferromagnetic bulk amorphous alloys prepared by casting processes. The multicomponent Fe-(Al,Ga)-(P,C,B,Si) alloys are amorphized in the bulk form with diameters up to 2 mm, and the temperature interval of the supercooled liquid region before crystallization is in the range of 50 to 67 K ...

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 ...

Amorphous silicon–tellurium alloys
Journal of Applied Physics, 1986Amorphous silicon–tellurium alloy thin films were fabricated by coevaporation over the composition range of 0–82 at. % Te. The electronic and optical properties of these films were systematically investigated over this same range of composition. The optical gap of these films was found to decrease monotonically with increasing Te content.

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 ...
