This paper presents a study on strain-induced martensitic transformation at room-temperature and 57°C in Cu - 11.8% Al - 0.6% Be alloy, which it is not only presented as austenitic at room temperature, but also it is deformed in martensitic state and it returns to its normal state when the load application is finished. Through this work, it is possible to quantify the residual deformation after interruption of the applied load during tensile testing, and maintaining the load for certain periods of time. The techniques used during this study were: X-ray diffraction, draw, optical microscopy, DSC. Statistical studies were carried out in order to achieve greater accuracy in interpretation of results.
