| dc.description.abstract | Thermal and mechanical treatment processes play a important role in shaping the properties and performance of Nikel-Titanium (Nitinol) alloys act like gripper. Nitinol alloys posses unique characteristics, such as shape memory effect and superelasticity, making them highly desirable in various industries, including biomedical, aerospace, and robotics. In this study, thermal and mechanical techniques were employed to modify the microstructure and enhance the functional properties of Nitinol, focusing on their effects on phase transformations and mechanical behaviour. The effect of thermal and mechanical treatment of Nitinol were analysed by two-way shape memory behaviour, by its reaction towards exposure of different temperature. As the result, annealing at very high temperature (550-600) °C caused the residual strain to increase and the transformation stress to decrease significantly over the first few cycles indicating functional behaviour degradation, it influences the transformation temperatures and hysteresis of the alloy, potentially shifting the phase transition temperatures and altering the shape memory effect and superelastic properties. Annealing of 51% Nitinol wire at 600°C for 30 minute is recommended as the best annealing condition for microstructure modification that allows for the redistribution of atoms within the Nitinol without oxidised. | |
