TL;DR: In this paper, a gas metal arc welding (GMAW) based wire arc additive manufacturing (WAAM) process has been employed to deposit 5-layered NiTi alloy on the Titanium substrate using Ni50.9Ti49.1 wire as the feedstock.

TL;DR: In this paper, the recoverable strain variation on cooling and heating under a stress was studied in the NiTi sample produced by wire arc additive manufacturing (WAAM), and the sample fracture occurred on cooling under 400 MPa in the middle part of the second layer due to the formation of cracks in the brittle Ti2Ni precipitates.

Role of Zr and thermomechanical treatment on phase transformation and functional properties of NiTi-based shape memory alloys
TL;DR: Zr addition to NiTi-based shape memory alloys suppresses martensitic phase transformation, enhances hardness, and exhibits pseudoelastic behavior with high stress plateau and recovered strain, while thermomechanical treatment improves functional properties.
