Net-Shape NiTi Shape Memory Alloy by Spark Plasma Sintering Method
An analysis of the shape memory effect of a NiTi alloy by using the spark plasma sintering approach has been carried out. Spark plasma sintering of Ti<sub>50</sub>Ni<sub>50</sub> powder (20–63 µm) at a temperature of 900 °C produced specimens showing good shape memory effects...
