NSF lists this award's end date as 31 October 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 February 2029.

Abstract

Nitinol is a remarkable binary alloy composed of nearly equal parts of nickel and titanium, with unique properties, such as superelasticity and shape memory. The alloy's distinct characteristics make it invaluable in various fields, including biomedical devices, aerospace engineering, and consumer electronics. However, micromachining Nitinol presents challenges due to its high strength, rapid work hardening, and…
