An overview of intermetallics research and application: Status of thermal spray coatings (2013, background): “Apart from the widely discussed strong properties of nitinol, the high costs for manufacturing large NiTi components and their manufacturing challenges [46-48] present restraints.”
3D printing of smart materials: A review on recent progresses in 4D printing (2015, background): “The shape memory properties of NiTi alloy are known to make it difficult for precise machining and it causes a significant amount of tool wear (Meier et al. 2009, Meier et al. 2012, Elahinia et al. 2012, Weinert and Petzoldt 2004).”
Welding and Joining of NiTi Shape Memory Alloys: A Review (2017, background): “The effect of the weld thermal cycle on the hardness of the different regions is not straightforward, as it also depends on the initial condition of the base material, that is, on the thermo-mechanical history of the material [194,195].”
Manufacturing and processing of NiTi implants: A review (2012, methodology): “Drilling of NiTi components with high cutting feeds and speeds helps extending the tool life and improve work piece quality although it results in an increased microhardness in the subsurface zones of the part [41].”
