چکیده مقاله
Electrical resistance variations of Ni50 9Ti49 1 shape memory wires were studied during aging at different temperatures via in situ electrical resistance measurments The results showed that during aging treatment, the cyclic behavior observed in electrical resistance variations which could be related to precipitation process The evaluation of transition temperatures has been studied after aging by differential scanning calorimetry DSC analysis Microstructural explorations have been performed by optical microscopy The results showed that depending on stress level around precipitates, two, three or four step martensitic transformations could be observed in DSC curves
