To obtain the two-way shape memory effect, a shot-peening treatment was applied. The shot-peening region works as a bias spring. In the previous report, it s showl that more than 0.2 % two-way strain could be obtained by this treatment. In this paper, fatigue property was examined. To this end, a fatigue machine was made, there specimens were immersed in hot and cold liquid alternately and cyclically. The results showed that the two-way strain reduced in the first several cycles but after the cycles the strain remained until at least 10,000 cycles.
