Recovery Mechanisms in a Compressed Ni-Ti Superelastic Alloy [PDF]
Materials Research, 2017 The present work studied the influence of annealing on a Ni-Ti alloy submitted to uniaxial compression. The stress-strain curve under compression showed the absence of the Stress-Induced-Martensite (SIM) plateau and 42% of remaining austenitic phase (B2).
