Ternary Ni-Fe-Co Alloys Nanowire Electrodeposition

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...

Sonochemical preparation of nanosized amorphous Fe-Ni alloys

Nanosized amorphous alloy powders of Fe20Ni80 , Fe40Ni60 , and Fe60Ni40 were prepared by sonochemical decomposition of solutions of volatile organic precursors, Fe~CO!5 and Ni~CO!4 in decalin, under an argon pressure of 100 to 150 kPa at 273 K. Magnetic susceptibility of Fe40Ni60 and Fe60Ni40 indicates blocking temperatures of 35 K and a magnetic particle size of about 6 nm. Thermogravimetric m...

Internal Friction in Fe-Co-Ni-Ti Shape Memory Alloys

The anomalies of the temperature dependences of the logarithmic decrement and eigen frequency of the free damped vibrations for Fe-Co-Ni-Ti shape memory alloys were first found in the vicinity of the reverse ay martensitic transformation. It was shown the damping capacity in the alloys investigated is comparable with that for TiNi based alloys.
