single
crystal shape memory alloy with the [100] orientation
aged at 600°C for 4 hours was investigated under both
tension and compression. A fully recoverable super elastic
strain was observed under both tension and compression
within the temperature range of -80 to 0°C. The fully
recoverable super elastic strain was achieved in tension
however the recoverability of super elasticity deteriorates
in compression. The tension-compression asymmetric
response is likely caused by different numbers of activated
martensite variants in tension and compression. Increasing
the aging times decrease the super elastic temperature
window and increase the transformation temperature.
