RESUMO
The presented work consists of a study for observation of the martensite kept in the transformation of martensite phase - austenite in a alloy of Ni - Al - V, with memory shape effect, into, a room temperature. We defined that the alloy with composition the 3,5% (in weigh) of nickel, presents better results when happens successive loading and downloading cancel though, 3,0% of deformation into a room temperature, back to austenite phase after retreat the load. Above 3,0% of deformation became evident the appearance of retrain martensite. For her identification it was necessary the development of on equipment to traction, as well as bodies of proofs dimensioned for that. The analyses were done through X rays diffraction of optical microscopy and rehearsal of traction.
