摘要：
Mechanical testing, transmission electron microscopy, X-ray and electrical resisitivity measurement were employed to study the superelasticity and microstructure of cold-rolled NiTi shape memory alloy subjected to electropulsing treatment (EPT) for more than 2.5 min. The best superelasticity with 8% of recovery strain is acquired due to recrystallization and aging of the NiTi alloy under electropulsing. The band microstructure of NiTi alloy cold-rolled has been changed to the equiaxed grains after EPT and the average size of NiTi alloy with the best superelasticity reaches to 40 nm. In addition, the X-ray pattern, electrical resistivity change and the upper plateau strength of the electropulsing processed NiTi alloy indicate the Ni4Ti3 and Ni3Ti precipitates are produced respectively for the NiTi alloy treated by electropulsing with the frequency of 150 and 350 Hz. Furthermore, the decrease of electrical resistivity of the NiTi alloy processed by with the frequency of 250 Hz shows the coherent relationship between austenite and Ni4Ti3 changes to the incoherent one in between.
