An analysis of the shape memory effect a NiTi alloy by using spark plasma sintering approach has been carried out. Spark Ti50Ni50 powder (20–63 µm) at temperature 900 °C produced specimens showing good effects. However, sample showed 2.5% porosity due to load 48 MPa. Furthermore, an apparent was recorded and were characterized uniformity in chemical composition alloys significant austenite phas...
