چکیده

Mn54Al44C2 forms the metastable L10 intermetallic compound, and exhibits ferromagnetic behavior after appropriate heat treatment. This material offers a low-cost, lightweight alternative to rare earth, alnico and ferrite magnets currently in use. Characterization techniques include vibrating sample magnetometry (VSM), X-Ray diffraction (XRD), optical microscopy and transmission electron microscopy (TEM), while mechanical milling, melt spinning and vacuum induction melting are routinely employed for alloy formation. Finally, we explore heat treatments under magnetic fields as a potential technique to tailor and enhance magnetic properties of interest.

Magnetic field-induced reversible actuation using ferromagnetic shape memory alloys

This paper presents a simple method to examine whether a ferromagnetic shape memory alloy can be used as an actuator by controlling the transformation temperature by magnetic field. Both Fe–Pd and NiAlCo alloys are studied. The analysis results show the recently discovered alloy of NiAlCo cannot be used. Although an Fe–Pd alloy can be used, in principle, for magnetic field actuation, the work e...

Experimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals

Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
