Out-of-plane magnetic patterning based on indentation-induced nanocrystallization of a metallic glass.
Periodic arrays of micrometer-sized ferromagnetic structures with perpendicular magnetic anisotropy are prepared by nanoindentation at the surface of a Fe(67.7)B(20)Cr(12)Nb(0.3) glassy ribbon initially showing in-plane magnetic anisotropy. The indented regions exhibit enhanced coercivity and saturation magnetization with respect to the surrounding nondeformed matrix. These effects are due to a...
متن کاملHigh pressure die casting of Fe-based metallic glass
Soft ferromagnetic Fe-based bulk metallic glass key-shaped specimens with a maximum and minimum width of 25.4 and 5 mm, respectively, were successfully produced using a high pressure die casting (HPDC) method, The influence of die material, alloy temperature and flow rate on the microstructure, thermal stability and soft ferromagnetic properties has been studied. The results suggest that a stee...
متن کاملReal-time, high-resolution study of nanocrystallization and fatigue cracking in a cyclically strained metallic glass.
Metallic glasses (MGs) exhibit greater elastic limit and stronger resistance to plastic deformation than their crystalline metal counterparts. Their capacity to withstand plastic straining is further enhanced at submicrometer length scales. For a range of microelectromechanical applications, the resistance of MGs to damage and cracking from thermal and mechanical stress or strain cycling under ...
متن کاملAb initio simulations of geometrical frustration in supercooled liquid Fe and Fe-based metallic glass
We investigate short range order in liquid and supercooled liquid Fe and Fe-based metallic glass using ab initio simulation methods. We analyze the data to quantify the degree of local icosahedral and polytetrahedral order and to understand the role of alloying in controlling the degree of geometric frustration. Comparing elemental Fe to Cu P. Ganesh and M. Widom, Phys. Rev. B 74, 134205 2006 w...
متن کاملMeasurement of low-temperature transport properties of Cu-based Cu-Zr-Ti bulk metallic glass
The transport properties, including electrical resistivity , thermopower S , and thermal conductivity of bulk metallic glass alloys Cu64Zr28.5Ti7.1, Cu62.3Zr23.7Ti10, Cu60.6Zr26.9Ti12.5 and Cu58.8Zr26.2Ti15 in the temperature range 10–300 K are reported. The temperature variations of electrical resistivity in these alloys, with a negative temperature coefficient, are found to be rather weak. Th...
