The invention discloses a preparation method for face-centered cubic structure titanium. The preparation method comprises the steps that 1, a pure titanium substrate is ground, then polishing treatment is conducted, and finally ultrasonic cleaning is conducted; 2, black tape is pasted on the surface of the pure titanium substrate obtained after ultrasonic cleaning, then two times of laser shock are conducted through a pulse laser, and black tape residual pieces are removed; and 3, the surface of the pure titanium substrate obtained after the black tape residual pieces are removed is coated with black paint, then one time of laser shock is conducted on the surface of the pure titanium substrate through the pulse laser, and the face-centered cubic structure titanium is obtained on the shock face of the pure titanium substrate obtained after laser shock. According to the preparation method, the face-centered cubic structure titanium is prepared through laser shock induction for the first time, the preparation method is simple, conditions are mild, experiment parameters are easy to control, and the face-centered cubic structure titanium is obtained on the shock face of the pure titanium substrate and is convenient to observe and study.
