Abstract
The functional fatigue properties of the high temperature shape memory alloy Ni503Ti25Hf24.7 were investigated under isobaric loading conditions. Full field measurements of transformation strains showed localization and heterogeneities in the deformation field which increased locally at higher stress levels. An incremental increase in the transformation strains, globally, was observed at low cycle count followed by an incremental degradation with continued loading. The response was associated with local changes in the deformation field which was strongly affected by the applied stress and the incremental accumulation of irrecoverable strains during thermal cycling.
