Abstract

The bamboo-structured Ni₄₅Co₅Mn_36.8In _13.2 fibers with martensitic transition temperature at room temperature were fabricated by melt spinning followed by annealing. A magnetic-field-induced reverse martensitic transformation from martensite to austenite with a shift of transformation temperature of 2.6 K/T was obtained in the microfibers. Different from the intrinsic brittleness evidenced in bulk alloy, the microfibers stored at 320 K (47 °C) were easily flexible, which is due to the fact that the formation of bamboo structures reduces the mismatch stress/strain near grain boundaries.
