A change from a memorized convex to a concave curvature between 10βΒ°C for the martensitic and 50βΒ°C for the austenitic transition is the important feature of a novel twoβdirectional shape TiNi memory alloy film fabricated by sputtering. The key to twoβdirectional actuation is Ti~3~Ni~4~ precipitate
