Observation of Physical Parameters in Cu-based SMA Aged Under Constant Pressure

Abstract

In this study, (wt%) Cu-13.5Al-4Ni shape memory alloy was used. The alloy samples were aged under the constant pressure of 558 MPa at different times. Physical parameters of Cu-13.5Al-4Ni alloy samples aged under constant pressure were examined. The effects on thermodynamic parameters were determined by differential scanning calorimetry (DSC). Microstructural examination was performed by X-ray diffraction (XRD). Metallographic observations were used to verify microstructural changes and microhardness measurements were taken. The physical parameters of the samples aged at different times under constant pressure were compared with the homogeneous sample.
