Abstract

Shape memory Ni55Mn20.6Ga24.4(at%) wires of approximately 200μm in diameter were produced by the in rotating water melt-spinning technique (INROWASP). The microstructure of Ni-Mn-Ga wire was changed from dendritic-like into bamboo grains structure with only one crystal in the radial direction by annealing. Annealed wires exhibit sharp and well-defined transformation between austenite and martensite, Ap to 82.4?"?, Mp to 70.5?"?. The crystal structure of annealed wires presents non-moderated martensite and preferred orientation at (622).
