The pseudoelastic behavior associated with the martensitic transformation (MT) of TiNi shape memory alloy under different types of strain variations has been investigated experimentally. The nestles are summarized as follows. (1) If strain varies within the MT region, the MT stress and the reverse transformation stress decrease under cyclic deformation. The properties of decrease in both kinds of transformation stress due to cyclic deformation do not depend on the amount of strain and the types of strain variation. (2) If strain varies beyond the completing points of the MT and the reverse transformation, the overshoot of the transformation stress appears at the starting points of the MT and the reverse transformation and the transformation stress decreases. The higher the temperature and the larger the maximum strain, the larger the amount of overshoot and the decrease in the transformation stress.
