Transformation Properties of Fe70-Pd30-XInX Shape Memory Melt-spun Ribbons

Microstructure and Magnetic Properties of Fe67.6-Pd32-In0.4 (at.%) Shape Memory Melt-Spun Ribbons

“…The phases of the ribbons were identified via X-ray diffraction (XRD), first at room temperature (Rigaku Geigerflex D/max B equipped with CuKα radiation source) and later at various temperatures for a narrower range of the diffraction angle (X-ray diffractometer Bruker D8) equipped with a Cu Kα radiation source and thermal chamber DSC350 for cooling down up to 173 K). The XRD for various temperatures was conducted in a temperature range from 173 K to 313 K. The transformation temperatures of the as-spun ribbons-martensite start, M s , martensite finish, M f , austenite start, A s , and austenite finish, A f -were determined as described in [26].…”

“…A small addition of Mn increased the transformation temperatures to as high as 371 K [22]. Moreover, the addition of In (<3 at.%) increased the transformation temperatures to above 300 K [26].…”

“…The influence of Ni [14,16], Co [16][17][18], Pt [17,19,20], Mn [21,22], Rh [23,24], Cu [21,25], In [26], Si [27], and Ga [28] on the properties of Fe-~30 at.% Pd-X alloys has been reported. The formation of bct martensite was found to be suppressed when alloying with Pt, Mn, Rh, or Cu.…”

“…The properties of Fe-Pd-In with various compositions with a focus on the influence of the addition of Indium on the transformation properties were reported in [26].…”
