Paper Abstract

The effects of aging and thermo-mechanical training on the two-way shape memory effect (TWSME) of a NiAl-Fe alloy have been investigated. It was found that the two-way shape memory property of NiAl-Fe alloy was increased obviously after training. The two-way shape recovery of NiAl-Fe specimens aged at 400 degree(s)C for 1 hour was higher than that of specimens without aging, and kept unchanged up to 1x103 heating-cooling cycles. The fatigue life of NiAl- Fe specimens aged at 400 degree(s)C for 1 hour showing TWSME was more than 1x103 cycles. The mechanisms for the effects of thermo-mechanical training, as well as aging precipitates on the TWSME have also been discussed.
