Abstract
Microstructure, mechanical properties and transformation temperature of neutron irradiated TiNi shape memory alloy have been investigated. The doses were on the order of 1020 to 1023 n/m2. All irradiations were performed below 423 K. Amorphization was confirmed by TEM after the irradiation of 1.2 × 1023 n/m2. The recovery behavior of the applied strain was drastically changed after the irradiation. The DTA peak slightly shifted to lower temperature and vanished. These results indicate that amorphous phase dominates the suppression of the martensitic transformation, and causes the change in the mechanical properties.
