Characterization of the superelastic effect in Cu-Al-Ni alloys elaborated by powder metallurgy

In this work the characterization of the superelastic effect in three diffe rent Cu-AI-Ni samples elaborated by power metallurgy is presented. Specific ally, the maximum values of superelasticity and the shape of the stress-str ess curves have been studied for the different samples. Moreover, the Claus ius-Clapeyron curve for each sample has been Obtained carrying out superela stic curves at different temperatures. The differences observed in the para meters studied in cacti sample have been related to the differences in the microstructure of each sample, generated by the changes introduced in the e laboration process.
