摘要
In this work the characterization of the superelastic effect in three different Cu-AI-Ni samples elaborated by power metallurgy is presented. Specifically, the maximum values of superelasticity and the shape of the stress-stress curves have been studied for the different samples. Moreover, the Clausius-Clapeyron curve for each sample has been Obtained carrying out superelastic curves at different temperatures. The differences observed in the parameters studied in cacti sample have been related to the differences in the microstructure of each sample, generated by the changes introduced in the elaboration process.
