Recently, (Fe-Co)-B-Si-Nb bulk metallic glasses (BMGs) were produced. Such BMGs exhibit high glass-forming ability (GFA) as well as good mechanical and magnetic properties. These alloys combine the advantages of functional and structural materials. The soft magnetic properties can be enhanced by nanocrystallization. To force the nanocrystallization, small content of Cu was added to the starting composition. In this article, {[(Fe 0.5 Co 0.5 ) 0.75 -Si 0.05 B 0.20 ] 0.96 Nb 0.04 } 100-x Cu x glassy alloys (x = 1, 2, and 3) were chosen for investigation. The GFA and the thermal stability of these alloys were evaluated. The effects of crystallization during heat-treatment processes on the phase evolution and the magnetic properties, including M s , H c , and T c , in these alloys were investigated. The phase analyses were done with the help of the X-ray diffraction patterns recorded in situ by using the synchrotron radiation in transmission configuration.

“…All magnetic properties were measured under DC magnetic field. From the previous published papers [11][12][13][14] it clearly results that for more than 0.5 at% Cu only fully amorphous ribbons can be produced. In this light, we tried to study (nano)composite samples with a small crystalline fraction, i.e.…”

The effect of Cu additions (1, 2 and 3 at.%) on the glass forming ability (GFA) and magnetic properties of [(Fe0.5Co0.5)0.75Si0.05B0.20]96Nb4 is studied. As the Cu content increases, the GFA deteriorates. The structure of the samples, as well as the crystallization behavior was in‐situ studied by means of synchrotron beam. The as‐cast 1 mm diameter rods are characterized by a mixture of (nano)‐crystals and amorphous matrix. Upon heating, the pre‐existing nuclei grow, without forming new crystalline phases. The magnetic properties are characteristic for soft magnetic materials. Despite that several crystalline magnetic phases can be identified in the as‐cast samples, only one single magnetic transition prior to complete crystallization could be identified upon heating. The values for saturation magnetization and for Curie temperature are relatively close for all samples. The initial permeability of the Cu containing samples seems to be higher than that for the fully amorphous [(Fe0.5Co0.5)0.75Si0.05B0.20]96Nb4 alloy (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

The effect of Cu addition on the soft magnetic properties of FeZrSi amorphous alloy was investigated by X-ray analysis, TEM observation, and B-H curve tracer. As a melt-spun amorphous ribbon sample was annealed above the crystallization onset temperature, very fine ¡-Fe particles smaller than ³15 nm were precipitated and uniformly distributed in an amorphous matrix. Cu addition to FeZrSi amorphous alloy annealed above the crystallization onset temperature resulted in decreased coercivity and increased saturation magnetization and permeability.
