This work investigates a new method referred to as “nano-skiving” for the fabrication of nano-scale shape memory alloys (SMAs). Nanoskiving is a new fabrication method that produces single copies or arrays of metallic nanostructures. The defining process is cutting slabs from a polymeric matrix containing embedded, more extended metal structures. The technique combines the deposition of thin films on flat or topographically patterned polymeric substrate using physical vapor methods with sectioning using an ultramicrotome. The resultant films are nano-scale in the z-dimension. This work describes the innovative approach to develop NiTi-based structures with at least two dimensions on the nanometer scale. The thermal-induced martensitic transformation is characterized via differential scanning calorimetry analysis. The crystallography and microstructure of as-deposited and annealed films is determined by both x-ray and electron-based methods. We spatially describe the atomic-/micro-structure, compositional, and dimensional uniformity.
