The authors would like to thank Missy Hazen of The Huck Institutes of the Life Sciences, The Pennsylvania State University for assisting the thin sectioning in an ultramicrotome. The ultramicrotomy was performed at The Pennsylvania State University Microscopy and Cytometry Facility. The BTIBD, RTA, stress-curvature measurement technique, optical microscopy, transmission electron microscopy, and spectroscopy were conducted at The Pennsylvania State University node of the National Science Foundation-funded National Nanotechnology Infrastructure Network. This work was supported by the National Science Foundation under Grant No. CMMI 1538354.

N2 - Nanoskiving is a novel nanofabrication technique to produce shape memory alloy nanowires. Our previous work was the first to successfully fabricate NiTi alloy nanowires using the top-down approach, which leverages thin film technology and ultramicrotomy for ultra-thin sectioning. For this work, we utilized biased target ion beam deposition technology to fabricate nanoscale (i.e., sub-micrometer) NiTi alloy thin films. In contrast to our previous work, rapid thermal annealing was employed for heat treatment, and the B2 austenite to R-phase martensitic transformation was confirmed using stress-temperature and diffraction measurements. The ultramicrotome was programmable and facilitated sectioning the films to produce nanowires with thickness-to-width ratios ranging from 4:1 to 16:1. Energy dispersive X-ray spectroscopy analysis confirmed the elemental Ni and Ti make-up of the wires. The findings exposed the nanowires exhibited a natural ribbon-like curvature, which depended on the thickness-to-width ratio. The results demonstrate nanoskiving is a potential nanofabrication technique for producing NiTi alloy nanowires that are continuous with an unprecedented length on the order of hundreds of micrometers.
