Magnetic resonance in amorphous iron-nickel alloys
An ESR study on amorphous FexNi80-xP20 alloys was performed at 1.1 Ghz and 9.3 GHz, where x=8, 10, and 16. Fe8Ni72P20 and Fe10Ni70P20 show paramagnetic to spin-glass transitions, while Fe16N~4P20 shows paramagnetic to ferromagnetic and ferromagnetic to spin-glass transitions. The lineshape, at both …

Percolation phenomena in amorphous iron-nickel alloys
… fields, are reported for the series of amorphous alloys (FepNi1_p)80P20. The iron-rich alloys are shown to be good ferromagnets, with the expected ferromagnetic critical behavior. Nickel, however, serves as a paramagnetic diluent. The amorphous structure permits the production of alloys that span …

Heavy-ion damage in copper, nickel and dilute nickel alloys
… of a displacement cascade, Cu, Ni, and dilute Ni alloys (Ni-Si and Ni-Al) have been irradiated with 50 and 100 keV heavy-ions (Kr$\sp+$ and Ni$\sp+$) at both 30 and 300K, and to doses ranging from 10$\sp{15}$-10$\sp{17}$ ions m$\sp{-2}$. The irradiations resulted in the formation of vacancy …

Environmental effects on the fatigue behavior of copper nickel alloys
… Mode III fatigue tests were performed on copper nickel alloys in helium, salt water environments. The hydrogen, oxygen, two alloys used air and in this investigation were 90-10 and 70-30 copper nickel. Both alloys contained iron which was added to improve the erosion corrosion resistance. The …
