    摘要： A shape memory alloy comprises Co, Ni and Al with a two-phase structure comprising a β-phase having a B2 structure and a γ-phase having an fcc structure, at least 40% by area of crystal grain boundaries of the β-phase being occupied by the γ-phase. The shape memory alloy can be produced by a first heat treatment step comprising heating at 1200 to 1350° C. for 0.1 to 50 hours and cooling at 0.1 to 1000° C./minute, and a second heat treatment step comprising heating at 1000 to 1320° C. for 0.1 to 50 hours and cooling at 10 to 10000° C./minute.
