Net-Shape NiTi Shape Memory Alloy by Spark Plasma Sintering Method

Applied Sciences, 2021
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 Ti50Ni50 powder (20–63 µm) at a temperature of 900 °C produced specimens showing good shape memory effects.

Cycling model for a NiTi Shape Memory Alloy

Procedia Structural Integrity, 2021
Shape memory alloys are more and more used in many fields of mechanics and medicine. The reason of the success is the ability to recover the initial shape also after high values of deformation. During the deformation, the SMA are able to change the structure from an initial structure, often named as austenite, to a final structure named martensite ...
