Martensitic transformation and magneto-strain in melt spun NiMnGaAl Ferromagnetic Shape Memory Alloys

Microstructural characterization and functional performance of Ni54Mn25Ga21-xDyx high-temperature shape memory alloys

“…Generally, two groups of elements are chosen -Co, Fe, or Ti with atomic sizes close to those of Ni, Mn and Ga elements [11][12][13], B, Al or rare earth (RE) elements (e.g. Tb, Gd, Dy) with a large difference in both atomic size and electronic structure from Ni, Mn and Ga elements [14][15][16][17][18]. Particularly, the latter group can contribute to the enhancement of magnetic or mechanical properties through refining grains and introducing B/Al/RE-rich precipitates.…”
